I think the speed makes you not collect stars... I went from lvl 2 all the way to the top... i got 5 stars... happens very often. Once you start going really fast. you stop collecting.... kinda lame..
what sucks is when u get ALL the blocks... and it still does the "damping" and you get stuck because a cicle with the arrow constantly is moving... then gotta restart... it should just move on once you get all the blocks.
yea... -5/5 cuz $400,000 is WAAAAY too much for a weapon where the most u get is $250 from some box wasted my time for an hour... only got to 100k... DUMB!
you should be able to sell the units. no indicator, can you die? i let 3 waves go by without dying... we should be able to read what all the units do even if we cant buy them. and can you upgrade the units?
