A wonderful revisit to the Bloons saga. When I booted it up I was afraid for a moment that it would be pay to play, but I'm glad that I can blast as much bloons as I feel like, whenever I feel like it :)
Axe-cellent game. Loved the humour of it. The gold bonus for health at the end of the round is a bit of a broken mechanic though, you can just keep the last guy alive and hide until your medpack has recharged! Maybe turn it into a "wave completed" bonus.
It's a fun little game, there seems to be a problem with challenge though. There is a ton of content for higher difficulty levels (better units to use), but the game doesn't really get harder fast enough!
