Cube Builder Game

Cube Builder puts the level-building tools in your hands before it lets you play. You lay down blocks to shape a platforming arena, then drop in traps and obstacles wherever you want the challenge to spike, in a layout you control from the ground up.

Once a level is built, you can run it yourself or hand it off so someone else has to survive whatever you designed. It's less about clearing pre-made stages and more about testing your own trap placement against a real attempt.

Controls

Move with WASD or the arrow keys. Placing blocks and traps while building is handled with mouse clicks.

Cube Builder suits players who enjoy level design as much as the platforming itself — build something devious, then see if it actually holds up.
