omfg too bad the game ended after wave 40 -.- ..
btw for those stuck on lvl 28: buy the charge laser and save it for that lvl.. also buy more base hp and ull make it. rest of the game is easy
kinda hard to see the small labyrinth, but I guess thats no good reason to give it a small rating, so im gonna give it 4/5. btw if u cant see the small maze , right click > zoom in :P
