The instructions are in the description of the game's page .
I initially envisioned it as a first person portal style puzzle game about using different tools to get a bullet to a target but when the jam started i had a flight to catch in a few hours and wasn't finished packing. While waiting for the plane I tried to get some work in but wasn't able to get much done other than first person shooting and a physics based bullet. On the plane I realized that making that sort of game with all the mechanics i had in mind just wasn't possible so when i got to my destination i used the systems i already made to make a fast paced shooter with bullet hell elements
