axcho is right on. I can see why some peeps might find if boring, but get into the later levels and it gets intense! beat the level 40 boss, I dare ya.

I'm telling you! The balls teleport when you're not looking!
Made it to level 41 with 103,876 points. I had to give up, it was simply driving me nuts. Now I have an overwhelming urge to stab things... Good game though!
This game is WAY too fun. Especially Apocalypse mode! My only problem with Apoc. is that I constantly make insanely big booms! ...Then some really tiny enemy flies right past me at light speed :-\
But you are definitely on to something here. An idea for a few upgrades: structures. Just a thought. Def. like RatMan's idea for bumpers :)
Bloody fun game, right up until level 38. It is bugging out so much I can't even play. Any time I try to teleport a cube it just returns to its origional position.
