Okay, 4th level is not easy to solve, but it's possible.
AI makes mistake when you lead it into left bottom corner, then kill all enemies one by one.
woohoo! Here's a winner.. our sound designer didn't even get past 3rd level :P. Congratulations! What about the next stages ?
Stuck on 7 level for an half hour, last level was almost simply rushing. AI looks like nice, but have behaviours where it can be splitted to less dangerous enemies groups, if you fix this, game really will be impossible to win.
hahaha I think people will hate us If we actually do that :P But.. good to know!! :D
how did you get past lvl 4?
