finally finished it... was terribly boring, onec yuo have the weapons upgraded, you're just sitting, as 100s of baloons come at u, no skill, just repetition...
balanced level 4 in harmony til whole bonus ran out, nof fall, no nothing, but still no perfect balance, they physics in this game are flawed 0/5 for that
There should be a Star-counter on the screen... getting the last badge is boring, and you have no idea how close you got, thus changing it from a game of skill to one of chance
keep on an eye on points for next level in Statistice... then play the first few levels, and keep using your upgrades, before going back to earlier levels to get extra points to level-up, using the upgrade to take more pts per hit becomes important..... hope this helps
