WASD to move the guy on left and moves for the guy on the left are 1 (Stonestrike), 2 (Tsunami), 3 (Lightning Strike). Stonestrike does the least damage but also has the least move wait after you use it. Vise Versa for Lightning Strike and Tsunami is in the middle. Arrows to move the guy on right and moves for the guy on the right are 8 (XDXD), 9 (Extended Punch), 0 (Moss Attack). XDXD does the least damage but also has the least move wait after you use it. Vise Versa for Moss Attack and Extended Punch is in the middle. Note: Numbers are the keys you press for the moves.
Thanks to @wolf361 for some of the inspiration and code. Everything else by me.
