Make a small playable game from one idea
The poster gave Manus 2.0 a single idea: an open-world game where music is your weapon. He says it built the 3D world, characters, combat, music and sound effects, then tested and published the game, which you can play from his post.

Make a small browser game from this idea: [IDEA]. Keep it to one level that takes about 5 minutes to play. Show the controls on screen, add sound effects and a restart button. Test it yourself, tell me about any bugs you couldn't fix, then publish it and send me the link.
