I tried it the other week. It was interesting, but ultimately didn't scratch the right itch. It fails completely if you're looking for a Minecraft-like experience. Unfortunately that's how everyone keeps trying to describe it. It's far more akin to Castlevania than anything... it just happens to have some rudimentary crafting and black placement elements involved. Definitely give it a try if you can, just don't go in expecting Minecraft in 2D.
