I like this! The mechanic is creative and gives lots of long term vs short term decisions. My main problem with the game is level 5, the purple level (I think it was called "The Cursed City"? Can't remember exactly). There's way too many areas where it's almost if not impossible to get hit withouth destroying enemies, causing the later parts of the stage to become infested.
I really like the game, but I think destroying enemies should be a plan B if you can't or don't want to dodge something, not required to go unharmed through a section.
