SO BUGGY at this point. If you lose a life on a level it often doesn't register when you pass 80%. Lots of times shapes aren't destroyed by boxing them in, they just hit the line you make and bounce off-screen. Almost impossible to play at this point. 2/5 for now.
Serious bug--the only weapon i can use, starting at level 6 or so, is the lead pipe--whenever I pick up anything else, it says ammunition undefined. So not fun to have nothing but a pipe....
Mildly entertaining, but is absurdly simple compared to any other defense game--not strategy whatsoever aside from counting out seeds. Also,desperately needs a restart button. 2/5
