Its very underrated but the gameplay seems quite interesting and reminds me of the old Link to the Past Zelda game. Lots of sidescrolling combined w/ strategy in an 8 bit environment. I couldn't ask for more. Also it has an expansion coming out in early 2014.
Yeah, I can't wait for that. I love how Issac's appearance changes with each new item you get, and just the overall theme of the game. I also love the art style of the game. It's dark and a bit disgusting at points, but it has this odd cutesy feel to it.
