Color Blocks

Color Blocks is a precision platformer from an independent developer, now released on Steam. The central rule is that a character can only stand on platforms of the same colour as themselves. Players switch between red, green and blue at any time, which changes which parts of a level are solid and which can be passed through. Where platforms overlap, their colours blend into new ones, creating routes that require more than one player to access. Changing colour while inside a platform triggers an ejection, with the physics system pushing the character out; this can be used deliberately or worked around.

The game can be played alone or with up to four people. In multiplayer, every participant is tied to the others by physics-based ropes, so jumps, falls and colour swaps affect the whole group. Players can pull one another across gaps and must coordinate colour changes. Levels also include launch pads, checkpoints and optional rising lava, with the goal being to reach a flag as quickly as possible. Two rope modes are available: coloured rope physics or a neutral rope, suited to different level designs.

Co-op is supported locally with a keyboard and up to three controllers on a single PC, through Steam Party friends-only lobbies with invites and synchronised level starts, and online over Steam using host-authoritative gameplay. A built-in level editor allows players to place platforms, goals, checkpoints, launch pads and lava, and the level select menu lists both factory levels and user creations. A speedrun timer records best times for each stage. Accessibility options include colourblind palettes for protanopia, deuteranopia, tritanopia and high contrast, which alter visuals only and leave gameplay unchanged. Controls can be fully rebound on keyboard, gamepads including Xbox and PlayStation controllers are supported via Steam Input, and menus can be navigated with mouse, keyboard or controller.
