Arrow keys for player 1 WASD for player 2. On the menu screen press the buttons to change each and and variable to create your own custom gameplay, and use arrow keys to swap pages. Down arrow and S does do something. In multiplayer, you respawn every level. This is currently in early development and may be buggy. Most of the current features are complete, but may still be changed. I still have dozens of customization options to add, and I am currently working on overall improvements. Please comment on any bugs!
