Indie developer Robot Monkey Brain today announced the release of the Bounce Castle Steam demo, arriving ahead of Steam Next Fest, which officially kicks off February 23 and runs through March 2. Early access to the demo is supported by a brand‑new animated trailer showcasing the game’s physics‑fueled, turn‑based strategy and combat in the most Robot Monkey Brain way possible: fun, frenetic, and wildly chaotic.

The Bounce Castle demo gives players early hands‑on access to two full Regions from the final game: the Forest and the Castle, each with a set of Standard Chambers capped off by a challenging Boss Chamber. Across both Regions, players will battle through three Standard Chambers and one Boss Chamber per Region, for a total of eight Chambers being offered in this demo. Each run pulls randomly from a pool of six unique Chamber designs per Region, providing players with a small taste of the replayability and variety Robot Monkey Brain has planned for the game’s release.

Bounce Castle is a physics-based strategy RPG where precision, planning, and chaos collide. Players carefully aim and sling their team of heroes across hazard-filled arenas, using a wide range of skills and abilities to outsmart and outclass enemies in an effort to protect the precious Flow Crystals, which power the player’s team of Heroes.

Each of the game’s several unique Regions presents players with a gauntlet of traps, puzzles, and tactical decisions, culminating in a colossal boss battle with members of the diabolical and uptight organization known as The Order.

Along the way, players can collect precious gold coins, which can be redeemed by paying a visit to the traveling merchant, where they can upgrade their heroes’ unique abilities between runs. With resources running thin and danger around every corner, every sling and ricochet comes with risk. Players will face gruesome goblins, slippery slimes, and skeletal scoundrels, not to mention tons of traps and curveballs that would absolutely love to ruin a good run. Each Region is a slingshot into the unknown, and every decision brings players one bounce closer to the showdown in the forsaken Throne Room.

Key Features

• Tactics Without the Grid: A tactical game with no grid and no hexes. Bounce around obstacles, ricochet shots, or boop enemies into pits. Think pinball meets pool meets mini‑golf, with swords and fireballs.
• Defend the Flow Crystals: Flow is the player’s main resource, so be sure to protect the Kingdom’s Flow Crystals at all costs. Run out of Flow, and it’s game over, pal. Game over.
• Physics Meets Strategy: Enemies telegraph their attacks, giving the player a chance to counter strategically. Sure, wiping them out is ideal, but limited Flow means clever plays will often win the day.
• A Hero’s Armory of Abilities: Discover dozens of abilities, each with its own brand of strategy and chaos. Blast foes away with Gust or line up precision shots with Piercing Arrow.
• An Ever-Changing Kingdom: Each Region features a variety of randomized Chambers, keeping every run feeling fresh. That means new layouts with new hazard placements for new surprises every run.
• Unlockable Teams: Complete achievements to earn Unlock Tokens and gain access to new Hero teams, each with unique skills, abilities, and mechanics.
