Arrow keys to make pushers, wasd to make cloners, tfgh to make deleters, ijkl to make pullers, and q to make push blocks, and e to make batteries. To pause, press p.

made all of this, and this is my 3rd attempt at making a machine building simulator. Please request any type of block that should be added to the game. I know that the controls are a bit hard, but if anyone has a better way to have one button for each type of block, I'm all ears.
