I just beat Little Inferno a few minutes ago, which I bought yesterday after it went on sale on Steam. What an intriguing little game. You basically just burn stuff, and then buy more stuff, and then burn that stuff, and it's surprisingly addicting! Not to mention the story is very bizarre, and somehow charming and creepy at the same time. I'm also really digging this song right now. I'm not sure that I'd recommend it for everyone, but if you enjoyed the type of humor from World of Goo or you've got some money to spare (it's $4 right now, which I'd say is perfect for this game), then you should consider checking it out. At the very least, it's a game that's unlike anything you've played before.
Meanwhile, I bought Bit.Trip Runner 2 last week, I'm still making my way through Shin Megami Tensei: Nocturne, and a co-worker of mine let me borrow his copy of Tomb Raider. So it looks like I'll be juggling my time between those three games for awhile! I'd like to finish Nocturne before moving on to the other two, but it's a looong game. I should be nearing the end though, I think... but who knows. Gotta catch all those demons!
