I was mainly responsible for programming the game's physics and enemies. I also implemented many other miscellaneous features such as the textboxes, collision detection, and various other polish.
I designed the main mechanic, namely the bouncy aspect of the game, and tweaked a lot of values and did constant play testing to make the game feel good. I also designed and implemented the enemies.
I was the concept artist and animator for all the characters and animations in the game, including the main character and all the enemies.
