Nice story and plenty of variation in game play — it's like 4 games in one.
I liked the music, and the sound effects were brutal but appropriate.
The art was great and really added to the story you set out to tell.
I found one set of spikes that didn't do any damage (level 2, somewhere in the NE section of the map). There was a spelling mistake on that level too, I think the word was "remember."
The chase sequence was cool, but it wasn't clear to me what I needed to do until I'd failed it. Maybe that could be clearer, with a character saying "catch him" or something.
The combat menu for the final fight was generally easy to use, but I suggest disabling the item button unless the character has an item, and also clearly indicating how to go through the menu. My initial thought was that the item menu was broken and I did like having to press Esc to back out, because I thought I might lose my game.
Overall, a fun little game with an interesting story, and well worth a play.
