Love the look and it's a great idea. I'll agree with the others that mentioned lag (I'm guessing assets were loading?) and the controls were a little wonky (clicking shot AND jumped and invert controls inverted both up and down, which I'd expect, but also side to side). However, reading other comments suggests that what I'm interpreting as shooting and jumping is actually recoil. If that's true, I'd agree that it's an interesting mechanic. Overall, though, good work! My kids LOVED the music, by the way :D
