The first badge I got on this game was literally the hard badge. I jumped in, figured things out as I went, and earned it easily. Only thing I'm wondering is why challenge 20 is nothing more than some recipe and not even a level.
*shakes head rapidly* That was a lot of fun. Keep up the good work. Though, you should probably make the enemies hit the corners a little more so players don't exploit that.
Cleared the challenge, badges, and game in 1,597 seconds. 110%. Very well done, I must say. You deserve a 5/5 rate from me. (And personally, I liked the upgrades, esp. the music in combat that upgraded with the graphics.)
Personally, i just enjoy listening to that song at the endgame, either ending. Beat it on Armor Games, played it again just for the achievements on here.
