Umm...no. Just no.
I don't know about advertising your upgrade system, which isn't really that original, just a bit different. Also, way too hard, and you should start each chapter with the same amount of lives each time (cause nanobeast gets repaired after each wave, right?). Lastly, there are some nasty glitch-bug-stickeykeys thing in this game that sometimes makes some of the keys on my keyboard stick, therefore I crash uncontrollably. So yeah
