I downloaded the demo and I really love the way you made this game. The sounds effects, music, the pretty maps...it's all awesome. I didn't make it far in the game though. I couldn't get past one of the "monsters" so I had to leave the game and I don't wish to start over.
You should make it possible to save the game and you should make sure the monsters don't block the player completely.
I loved the game, it's just a shame that I didn't make it so far.
