Also, if you are trying to get all gold, don't EVER use super bomb; the bloons popped by it will not count toward your score, which is SO annoying when the bomb spawns right where you are standing.
I had really big bug with Unihound's light beam attack. Its power down effect seems to be stackable AND persistent even after the effect is suppose to end. This makes any match too easy; I can just spam my light beam and enemy attacks will be reduced to 10s permanently. Anyone else has this issue? If so, please fix it.
