Ahhh this should be easy, I mean it's just like brick breaker except everything is round and red.
*5 minutes into endurance mode* PLEASE MAKE THE PAIN STOP
I remember playing this game like a year ago, and I couldn't even get near getting the impossible badge. Now after a full 12 months of playing bullet hell games all the time, this feat was made possible in only 2 attempts! Wish everyone luck, just don't give up!
I just had 2 normal turrets (Fully upgraded) 2 missle turrets (Fully upgraded) 2 Arch lightning turrets (Fully upgraded) and a bunch of other stuff that was full upgraded. Only problem with the game is it took me only 10 minutes and was WAY to easy.
The only reason I got so much cash fast, is because I got over kill, then the lazer cannon. Once I did that, I got like 30k in the first part of the 2nd day. Oh btw, if you make a sequal to this game, please make it harder :P But this is an awesome game, so don't think I didn't like it.
