make undo button, i got pissed off many times because i click one more time on some arrow key (and it was in rush because i wanted to finish lvl sooner and not because i didn't know how to solve it)... until you make UNDO BUTTON you have 1/5 from me... make games that will relax and be fun to people, not games that makes me stressful and angry !!!
add fcking suicide button !!!!!! now i have to play from lvl 1 because i got stuck at lvl 13... i will get badges, but your game gets 1/5 rating because of this !!!!
fck this, i played this for 2.5 hours to get up to 1729 distance, then had to restart browser because game started to lag and when it came back i had very nice surprise - no upgrades were saved... well for this i'm changing rating for this crap game to 1/5...
no selling units -> here's one fat 1 rating for your game... i don't like being forced to play level over and over again just to be able to setup strategy for it (unless i know what eaech wave stats are i can't set it up perfectly)... selling units allows me to do it on fly, without it game requires exponentially more time...
Poor copy of Sonny game, plus final boss can't be defeated unless you start building char with previous knowledge of game... and i don't give a damn to play whole game from start just to beat it... 1/5 from me... advice - get 1st and 2nd badge, other two are wasting of time comapred to points you'll get...
