Pretty nice! My computer doesnt like it a bit but otherwise its pretty neat. Kinda easy though, or its just me getting lucky and getting to the 4-BOSS L1 on my second attempt (i didnt die while fighting but just accepted their deal. I was playing as the ship that can go invisible). Maybe you can add some lasers or something, because if the tags dont lie its made on game maker so lasers are pretty easy to make.
