Thanks! Yeah I know that you can also use R and W, but the whole game can be played with just the left mouse button. The other buttons are there because I initially made this game for another jam, but they are totally optional.

Hi! TCubix is right, the game use at least a mouse button AND mouse movement, which is the equivalent of several buttons! (up, left, right and down)
Many games can be played with mouse movement and one mouse button. The challenge here is to be able to play with one keyboard key (or gamepad, whatever).
Thanks for your interest in the jam, but for next year remember that =)
