Fun but....
.... it was too hard when the green guys and those orange worm came together.
If you didn't have a ball big enough it's a pain hitting them, and if you do not have enough power and hit something, the ball slows down. And if it by any chance bounces to another thing, the next creep will reach the pins (mainly the green ones). Even if the ball comes back in time, it's too hard to know where it is when it respawns. And due yo stress you are most likely to miss that one shot which will cause this to happen again. So the best thing you could do was to just wait for one or two creeps pass and try to keep the others off.
