I think for a flash chess game, it's really good. The engine isn't too difficult to beat, but I believe the engine was just a side feature to the puzzles. I really like the user interface.

Awesome game! Graphics are amazing, some minor bugs but great game. Hope the next one is longer!

Awesome game!

Great work, but a slighly annoying bug. When I died after the checkpoint when running away from the cart, I could no longer move gretel or shoot her slingshot, so I got stuck.
