I've recently finished playing VVVVVV and it was friggin' awesome... but I wanna try out a few more 2D games of that type. Some recommendations on where to start would really help
I Wanna Be The Guy is good, if you haven't played it. It's stupidly hard though. I heard about it from Derek and Minus on the boards. Another good one is Meat Boy on Newgrounds.com. Or you could always download some SNES/GBA roms.
The full version of Super Meat Boy that I downloaded from Demonoid crashes. Apparently there are a lot of bugs still on the process of getting fixed. I've played the flash version a bit and it's pretty fucking awesome.
