Reddit, I'm bored, what are some good games that I can play?

Hey guys, Just note beforehand that I have a really shitty computer that overheats if I play a game that's too intense (read:Skyrim, Portal and From Dust), so I can't play any of the games I currently own.

I'm a big fan of platformers like Braid, Meatboy, Trine, etc.

So Reddit, what are you're suggestions?

Edit: Got about 5 new game from you're suggestions / steams suggestions. Cheers Reddit =)
