I'm almost done with Adventure Time, which has been a disappointment. I don't know why I expected a game about a kid's cartoon show to be challenging to someone in their mid-20s.
On a brighter note, I'm several hours into Mutant Mudds and am loving it. The fifth stage is kicking my ass, and that's what I like in my platformers.
I also very recently bought The Legendary Starfy, because it was only $7 and also because OHMYGOD SOOO CUUUUUTE
