Good to see this game up on NG too!
The game mechanics are pretty solid, the levels are challenging, and the speedrun feature adds replay value. My main critique with most of your games, however, is that the playable ending screens don't make sense. There's less of a sense of accomplishment with this one than there is an odd twist on the gameplay leading to a strange downer ending. That's a tiny nitpick, though! Great game overall!
