This is an awesome game, much better than EBF3, but the gameplay feels a lot slower than the other EBF games. Like, the battles seems like it's in slow motion compared to EBF3 and the like.
The game is broken. There's a point in which if you collect blops it doesn't register them and when you finish the level it deletes all the blop cash you have collected during the run. When this starts to happen it happens on every level afterwards Also, there have been parts in which it locks the next upgrade in the chain unless you buy the first upgrade again, meaning you have to buy the upgrade you have AND it's prerequisites that you have ALREADY bought, just to get the next one. Oh, and you can't because the blop cash thing is broken. I never thought a Bloons game could be so astronomically crap.
