gentle push: 1) make sure you didn't leave any vomit up on the ledges
2) vary your timing for when you start puking relative to when you jump, optimum is just after you start to jump
21 is indeed a pain. Not exactly sure how I won, I was down to one target and one shot, got distracted and had to do something in a different window...came back, she was dead. Old age?
Meh. It is kinda silly that there are three "lines" of battle. The computer will block two lines with towers, but I can just run my entire team through the third line to take out his base...dumb. Also, ranged units can't provide support fire, and fast units can't move past slow units, so queueing up more than one unit in a line is almost worthless. I also don't believe some of the wisdom the game gives about which units beat other units...
It's Epic War 2, only a little less annoying since you can (kind of) control the movement of your troops.
Pretty sure the Stimulus Package badge is broken.
medium badge is glitched...played all the way through the game (including wrapping around to level 1...wtf?) and somehow did not get it.
After you fight the wizard-penguin-boss, almost every level is identical, which is boring and not fun.
Balance issues with weapons...rocket launcher goes through ammo way too fast. Chainsaw should probably go through ammo a touch slower, or do a touch more damage, to be balanced relative to the chaingun. It's still useful, mind, but the balance feels off.
