I thought it was a standard by now to have the game be able to scale to zoom? Please, it's annoying to play in a small window, and I can't even zoom in the browser without your game glitching out :)
A tip for those having problems getting the hard badge on Mount Magma: buy three Dart Monkeys from the starter money and stack them on one side near eachother and keep upgrading their popping power. Make sure to set the target priority to "strong". Some individuals will go through but don't bother yourself. You will need to use pineapples to break the metal ballons. Once you think you're set, gather enough money to buy and upgrade a Bomb Tower, then it's all up to you.
Level 15 compared to level 14 was extremely easy... I've done my entire grind from lvl 1 to lvl 19 on Medic on level 14... that was a nightmare! 15 level beaten on 1st try though :P. 3/5 because of the long, unnecessary grind for a single player game. You just dragged the game story because you didn't feel like creating more levels this way, didn't ya?
Hey, I didn't see any awsum life-draining in later levels! Maybe because I used two 5-spreads and one small bubble flying around the arena shooting the middle? Pff
you don't have to stop every half a minute if you don't want to. you can get upgrades after driver select after you die like the first game.
