Looked at the demo and this looks rad! I really dig the graphics, they're very nice and I like the different things going on, from a sunny village to this dark creepy dungeon, how it's all done well.
Watching the trailer was sweet, but the sound effect you've got for opening gates- it's really loud, and a lot longer than the opening takes. I was also curious about the tiles you move with your mouse- do they make it possible to get stuck at certain points? I feel like I'd shoot a tile off one way without thinking, and then wouldn't be able to get it back, and I'd be stuck. I just couldn't tell if that was addressed because the trailers, the player made no mistakes whatsoever, really. I also didn't see what happens if you get hurt, or fall or something.
Other than those two small things, though I'm really digging this, especially the look of it.
