Chapter 01 The promise

You can always come back and make progress here.

Galespun is a single-player dungeon adventure set among floating islands, extraordinary companions and ports with lives of their own. At its heart is a particular kind of anticipation: the next expedition might bring back the rare component you have been searching for, the beginning of a powerful build, or the means to take your airship somewhere new. The feeling we want a player to leave with is simple: I want to go back to this world.

We are designing for people who love the depth of an action RPG but have limited time to untangle one. A parent fitting an adventure around a busy day, a younger player discovering a first favorite companion, and someone who enjoys experimenting with unusual builds should all find an inviting way in. Depth should reveal itself through play: a move that suddenly clicks, a companion who changes how a dungeon feels, a find that makes the next goal visible.

The promise begins in the player’s hands. Movement needs to respond cleanly. Attacks need satisfying sound and impact. The path from a modest start to a powerful run needs to be readable. And there is a second promise underneath: a bad run never makes you weaker than you were. You can always come back to this world and make progress.

Chapter 03 Your first companion

Start as one. Discover what two can become.

The trainer enters that first dungeon alone. Before there is a roster, before elaborate combinations, there is one person learning how to move through danger. Finding the first companion is the first major power spike. It should feel like a complete increase in what you can do: a new presence beside you, a new source of power, and a relationship you learn through play rather than through a tutorial.

Once that partnership begins, combat centers on one active companion. You control the trainer while your companion follows and attacks, with powers you deliberately trigger. Only the active companion gains experience during a run, so training someone new is always an intentional choice. Unlocking more companions and gaining the ability to switch between them is meant to be one of the most satisfying rewards in the game.

Later companions can arrive through quests, dungeon encounters, discoveries and recruitment. A roster of roughly twenty to twenty-five companions could be enough if each one feels distinct: elemental families such as wind, earth, leaf and water share themes, while each individual has its own mechanics and a clear reason to choose it. Some companions may simply be stronger than others. A powerful newcomer usually starts with little permanent progression, so bringing it back to an earlier dungeon becomes a training project and gives familiar places a new purpose.

Chapter 05 The dungeon journey

Learn a place. Then decide how hard to push it.

A dungeon is both a test of your current power and a place you gradually understand. The first version uses authored maps. Rooms can have different conditions for success, but each should be clear enough that familiarity becomes mastery. Deeper areas change hazards, layouts, enemy behavior and pressure on resources, and rarer materials wait further down.

A dungeon can also be pushed. Progress in cities and the wider world raises how hard a dungeon can become. Within that ceiling, you can spend resources to temporarily juice a single run: stronger monsters, more enemies, elites, altered attacks or hazards. The danger should be real, not just a larger number. The reward is a better chance at the specific material you came for.

Players should know enough to choose a dungeon for a purpose. A dungeon can be known for particular chase materials, such as a rare petal, an evolution ingredient or a permanent-progression component, while exact drops stay uncertain. The loop we want is simple to say and hard to master: raise your access, spend resources, increase the danger, chase a specific reward, then extract or lose the haul.

Chapter 07 Risk & returning

Leave with what you have, or push deeper?

Finding something valuable changes the feeling of a dungeon. Until then, pushing on is easy to justify. Once you are carrying a resource that could unlock the next step, the same choice acquires weight. You cannot leave at any moment. Extraction happens at designated exits and safe points, so taking one is a real decision. A rare emergency escape could exist later.

Defeat costs the unextracted haul and the temporary experience earned in that run. It never costs the progress you had already secured: banked money, locked-in stats, permanent companion growth and stored resources are safe. There is no death spiral. If you fail, you keep your permanent state and try again, using basic expeditions to rebuild supplies if you need to. A later idea is a rare, hard-won way to protect a single chosen item from loss.

Carrying capacity is part of that tension. Your pack only holds so much. When a valuable find does not fit, you choose what to keep and what to leave behind; the game does not quietly solve it for you. Early scarcity is intentional, and it gives every later capacity upgrade meaning.

The run ends.
Your journey carries on.

Chapter 09 Progress that stays

A powerful run ends. A stronger beginning remains.

Galespun separates the excitement of becoming powerful inside a run from the slower satisfaction of strengthening your starting point. A companion might enter a dungeon at level ten and reach twenty during the run. When you leave, it returns to ten. The materials you extracted can then be crafted into permanent progression that raises its starting level, perhaps to twelve. The next run starts from a higher floor, and temporary levels carry you further still.

Permanent evolution is rare and milestone-like. It needs both a permanent level threshold and a rare crafted evolution item, made from a dungeon find plus materials gathered through play and possibly trade. The feeling we want is that you raised this companion and completed a real material chase before it changed. Temporary evolution within a run may also exist; how the two relate is still open.

The trainer grows differently. A permanent, skill-tree-like layer makes the trainer better at enabling companions through faster cooldowns, longer range, wider area effects, stronger critical hits, and support, healing or defense. Permanent power should build slowly at first and much faster toward the end. It should always increase what you can attempt without ever making you invulnerable.

Chapter 11 People & belonging

Make room for someone, and they bring their craft.

The first person you rescue unlocks crafting, and crafting is now central to the whole game. It is how extracted materials become higher starting levels, evolution items and other long-term power. Without it, a successful run is just a full bag. With it, a run becomes a stronger beginning.

Specialists need somewhere to work. A crafter, artificer or armor forger joins when the ship has space and the right station for their role. Building that room is part of inviting them. Crew management stays light: their services lean passive, so the ship feels more capable without becoming a management game.

Crew members can have histories with particular ports and ties to people there. For now those relationships are mostly flavor, with room for deeper effects later. Companions contribute a different kind of attachment. Bond capacity grows slowly, and the last slots should be major achievements. Finding a rare companion when your bonds are full should force a real choice. Physical habitats are deferred; bond capacity is enough for now.

Chapter 13 How it fits together

Every return creates the next reason to leave.

Taken together, these systems describe a rhythm. You choose a dungeon for what it might give you, choose the stakes, and perhaps push it harder than before. The run offers quick powers, new pressures and materials to pursue. As your pack fills, returning begins to compete with the chance of finding more. What you bring home moves through crafting, companion growth, the ship or a distant market, and the next run starts from a stronger floor.

A player chasing an evolution ingredient may learn one dungeon and juice it deliberately. Someone training a new companion may revisit easier places. Another may carry leaf materials across the kingdom. These are examples of connections the design should support, not a fixed itinerary.

That rhythm is also the test for every system we add. If a system’s complexity starts distracting from the enjoyable core, it gets simpler or it goes. One representative interaction that proves the idea is better than a complete ecosystem nobody asked for.

Chapter 15 Built in the open

Learn by making a real game, then share what we learn.

Galespun has a second purpose beside being a good game. It is a way to learn game development by building something real, then share what it teaches with the wider community. The project should stay interesting enough that its creator keeps learning, and frequent visible updates help the community follow along.

Playtests are small and frequent: short sessions, and longer ones of about thirty minutes. Afterward, the questions are simple: What was fun? What wasn’t? What did you like? What didn’t you like? What do you want to see?

The most important evidence is what players do. Are they visibly having fun? Do they want to keep going, and do they want to come back? Interest in sharing clips is a welcome secondary signal, never a substitute. Feedback can stay outside the game, and analytics are not needed on day one. AI tools, including Codex and Claude, are part of how the game is made, and the animation and asset pipeline is expected to be one of the biggest things to learn.
