Oh man, bullet really do go brrrr with the powerup.
I like your game, but it has some rough edges. The music was alright, but too slow, the sfx was not really good imo, and it's really easy, especially when bullet go brrrr, but even without I feel like there was no real challenge. Way too many healthdrops and the enemies themselfs didn't feel challenging. The lighting is somewhat over the top, but thats a subjective preference I suppose.
Other than that: I like the idea, it's simple and works well. Nice :)
