Two decades of gaming and dropping almost every game in my path. RPGs, SHMUPs, Action, Adventure, Strategy, they all usually fall before me. Previously, there was only one game I have not been capable of beating, that being Populous, the hardest game ever made. Well, it used to be at least, because now there is a new game with that title, this one. I Wanna Be The Guy is the hardest game ever designed, more difficult than even the most insane Bullet Hell SHMUPs, and I simply can't beat it.
I get to The Guy's fifth form (second "big" phase), and I get creamed every single time, I just can't dodge all the crap he throws at you. So congratulations, you have made the second game I simply can't beat, and I name I Wanna Be The Guy the new World Heavyweight Champion of Impossible Games.
Disclaimer: This does not count "special challenges" like "beat a game with no continues" or "NSG FFX" and other such stuff, though this game would still win because Impossible Mode really is impossible.
