So, there are two games I've been searching for for a while now, both of which I know for a fact are--or at least were--on NG.
The first I don't remember much about, except that it was a platformer and the characters were sticks--the player controlled a white stick figure, and the enemies were crazy red ones that ran at you on all fours when you got too close to them. The most distinctive thing I remember is that there was a portion of the game where you got to play as one of the crazy red guys yourself. The game had a bit of a psychological atmosphere to it, one of those "exploring the concept of insanity" kind of things, or something along those lines.
The other game is also a platformer. Pixelated graphics, if I remember correctly. You play as a female vampire and are guided by some kind of flame spirit that talks to you through candles. There's a heavy emphasis on running around on rooftops and being stealthy and badass, with your speed and jump height fueled by the consumption of blood--you can sneak up on humans and drain them of blood to increase your agility and to heal yourself.
If any of this rings a bell, I'd really appreciate any assistance!
