Dang, what a fun game! Just beat the whole thing, I might go back and try it again! The concept was really creative, the mechanics were perfectly fluid, the graphics and the sound design were all incredible!
The only point of contention I have is the player's idle sprite - it looks the same whether you're facing left or right, which can make it difficult to line up the laser before charging.
I'd love to see someone speedrun this game someday, I bet there were a lot of tricks with the level timing that I missed!
