Its a fun content till wave 200. Afterwards its just the same. Got a memory error at wave 936 which made me a bit sad. but the bonus money for next turn made it even ;) Bad thing now: the game is just broke, once you reach lvl 200+ cause its just too easy getting grav or earth to 100% (whit 6 attackspeed you are fine with 20% but who cares^^) Not to mention the 100k res/wave
XmmmX99 has just published the balance update! It's a lot more challenging and fun. Please let us know if you think it's still to easy ;)
