Lv.10 Grenade, Health Pack and EMP cost 0. Grenade is fairly useless around wave 90+. Prices are bloated even after the backpack update, though.
Quitting a game right when it starts gives the same money as beating the wave.
Mags are useless since mid game. Gun body looks like it's useless throughout the game. More so when two shields cover each other.
Wave 30 is extremely tougher than any of the previous ones. A more reasonable curve would be advisable. The number of troops gets silly on wave 95. I bet older computers lag horribly or crash at that stage (if not earlier) and the stack of troops looks silly.
People complain about being stuck due to dying while killing a boss. Never experienced, but it should be addressed.
About bosses, the axes one is stupidly powerful, while the shield one is (just as) stupidly weak. Missile guy is fine.
Not having missions after wave 30 (likely earlier) is sad.
Game gets kinda boring after a while, but is a nice time waster.
I reckon it's a 4/5.
