I am a regular viewer of Cobaltstreak, he mainly streams Binding of Isaac (and he is incredible at the game) but also branches out into other games. Last night he debuted a new BoI-esque roguelike called Our Darker Purpose. It has a Tim Burton vibe and expands on BoI by including levels and the ability to earn tickets as your beat levels and power up your character in between playthroughs. I picked it up today and have really been enjoying it. It is $10 through Feb 5th and I highly recommend it if you put any amount of time into BoI.
