Good Game, but it gets old.
It's a great game :). I love the concept of editing your own arenas, enemies, and your own tank. It's very nice feature. However after playing around (about 7 arenas into the game) you get really BORED. It's just arena after arena of bubbles blasting eachother, even the editing and all that extra usermade arenas can't make up for that. I would definitely love to see more variety in BT3 :).
Another issue, gunpoints. You get them a lot slower than bubblepoints. That's a problem. I'd end up with a ton of bubble points, but barely any gunpoints! Which is by the way, more important. It's the firepower, and getting it so slow really brings this game down.
Also the old system, versus this new hp system, is interesting. I don't prefer either so it's your choice which to put in BT3. Also what's with the red? How about an option (to unlock) so you can change the color? That would be nice :). More music too! :D
Overall a great game, I look forward to BT3!
