If the offer still stands, here's my game.
I guess the best genre to fit it in is top down shooter, but you'll be using the gun for movement more than anything else. It's technically endless too, so no pressure on making a longer video to fully complete it.
I'm completely solo, and only really started game-dev this summer. And I'm currently working on a free improved version, which already makes the jam version look like a basic demo.
Thanks!
