Awesome work! Everything in this came together super well. The pixel art is excellent -- the sel-out and aliased sprites look amazing against the backgrounds. The music is great. Super catchy tunes. The gameplay was challenging but really well-balanced. Every level beaten felt like a hard-earned victory. My only feedback would be that the jetpack mode felt too hard. I only managed to beat one level using it and it was just because it was balanced out with zero-G. I thought the floor-is-lava mode was also too difficult, but then I managed to get my win on level 12 with it active, so I think that one's probably good. Anyway, really loved this. Great work to everyone who put it together!
