Bouncy Blob by NuSan is one button tiny physic based platformer made for PICO-1K Jam 2022. The style of the game is rather simple, oriented with a touch of arcade.
You can use any button (like c, v or arrow keys) to jump, you have infinite double jumps and have to reach the end of the randomized tunnel in each level. The number at the top is a timer which shows how much time you have taken to finish each level.
