After 3 runs, this was my best. Decided to give it a shot again after the first one (with more than 50 deaths and about 450 kills) just for the secret level... although I couldn't find it.
Super cool mechanics. Super annoying little one spawning at the worst possible moments. Excelent level design. I'm happy I've played it.
Oohhh, and the spikes... how much I hate them!
Would love so powerups for me, not just for the enemies ;)
Great game! Congratulations!
