Quietus is a tough platformer which feels like a cross between Meat Boy and the castle levels from the 2D Super Mario games. You play a guy who has hanged himself, then been throw into a gauntlet in Hell by Death.

There's swinging spike balls, things with teeth that spring from the ground, ghostly beings and other sorts of nasty things. It starts off simple, then gets fiendishly difficult, with precision platforming essential. There are 40 levels in total, and some of the levels contain chests which can be opened by pressing down in front of them. I didn't have the skill to reach the end of the game, so I'm not exactly sure what the stuff in the chests does. Feel free to let me know in the comments!
