There are so many great submissions!
I'm trying to play and rate them in my spare time.
Here is my game: https://itch.io/jam/gmtk-2019/rate/461622
My game is called bounce shot and is a one button game.
You have one bullet to shoot at an enemy and you have to bounce it of the walls to get around obstacles. The enemy dies in one hit, but so do you, so be careful where it bounces. You can charge your shot to have it bounce more, increasing the chance it might bounce back to you, but also increasing your kill score, if your bullet uses more of its bounces.
