I really like the idea and the graphic stile of your game. What I am missing is a tutorial or a How-To-Play section where they keybindings are explained. I started and didn't knew how I can do anything until I figured out that I can controll the character with the arrow-keys. But the movement is very fun and as I got into the game I raged a little bit at some places^^
Also I would have liked to have all the game data in a zip-file or somehting like that so I can download the game and have everything together.
