I've made a game jam idea generator using Construct 3. This tool will help you to make a game when you join in a game jam without a theme or a limitation or both of them. Unlike any other game idea generator, there is an AI who will make you annoyed from his text and make sure your heart races a lot. Also, did you know that you can also input your own theme and limitation? That way, there are more options to your advantage.
There will also be an AI who will accompany you. He may be annoying, but that's just who he is; an annoying AI who will make sure you know that he's alive, even if you don't want to.
