Good but terribly laggy late game
Fantastic game, great fun. Choosing between the colours was a different twist. Nothing remarkably special but it was definitely a new twist on your typical TD. Worth playing, but not quite good enough to come back to.
But the game puts the emphasis too much on spamming all kinds of towers rather than upgrading which led to horrific lag around the wave 30 mark. It would be better to add more levels to the towers so instead of places twenty gold towers, just a couple could be upgraded to achieve the same effect.
I also ran into a coupla bugs;
-The puddle thing you put on the path can be upgraded at 0 cost, although no difference is made anyway (it looks better though :P)
-If you fully upgrade a bog tower and sell it you get infinite money
