Pretty sweet game. Not too difficult in any aspect, but still difficult enough to feel like you earned your escape and had fun doing it. I did run into a couple of bugs (but there are plenty of lives in the game for each level so no biggie). First, as Dantana12 mentioned, I did have occasion where I moved away from the monster (such that they are on the tile I was just on) where it killed me. No, I wasn't attempting to move through the monster, and it only happened once. Every other time the monster moved in sync with me and did not kill me. I did not attempt to recreate this. Second, in one of the levels (second to the last I believe) the princess and one of the monsters became invisible and no longer interacted with the game objects, well most of the objects, I eventually ran into a monster that was in an area I shouldn't have been able to get to, this killed me. Again, this bug only happened once, I did not attempt to recreate the error, and the next run played perfectly.
Solid 4.5 star game, only real criticism is I wish there was more of it. Keep up the great work!
