one sniper all the way up to at 4-2 makes some later rounds on easy so simple. ceramic bloons come out at exactly the same rate it fires. you just have to sit and wait for the MOABs.
This game has some serious bugs. I got a far way in, and then I died AS i hit a checkpoint pad. I permantently turned into the little flying black dot. I can move through objects, and i control it the same way I do the line. I now have to restart or just leave :(
I don't care if it would b totally worthless, I still think you hould totally be able to place bubble gunners. If that is what it says I'm researching, ("unlocks a new unit in game") then I want to get a unit.
Excluding the slightly confusing and awkward control system (not that I can think of any better way to have it) it's really an amazingly original game.
For all of the people complaining about scren size, I have one very simple peice of advice: 1) Go to the simulator. 2) Simulate a battle. 3) notice that the screen it shows looks exactly like the top of the screen in the normal game. 4) Play in the new screen.
This should help with the screen.
