Fun game and fun take on the theme as well, i like the use of lights it really adds to the atmosphere and pairs nicely with the minimalist artstyle, music is awesome and i'm not surprised, Newgrounds has some amazing stuff out there i.m.o so it was a good choice licensing an artist from there ^^
i also like that this was more of a free roam movement game rather than a classic auto scroll shmup, if i'd have to nitpick i'd say the only negative point for me were the trianglular enemies that feel a bit eratic and hard to predict, other than that it's solid overall, simple to pickup and play and fun
Good job :)
