My poor fingers...

I was a little bit disappointed when I killed the lava boss and the game suddenly ends with an error. Than I figured... it is a demo, right... heh. I really enjoied playing this game since I love tiny graphics and I love deadly mazes. Although I managed to finish the demo, the continous tapping of the arrows to move quickly through some kind of terrains is a real fingerache. I rated 5 this demo excluding sounds and interface and counting only on graphics, gameplay and story. Graphics are very lovely like the story that is a classic that never dies but the gameplay it's very tedious.

Try to move player with smooth interpolation to a tile to another maybe adding some leg-runnig on temporary tiles and a nice jumping on normal ones... I'll love it ^_^

An editor could be an improvement to longevity that in this demo lacks a bit for this kind of games and I think you should double or triple the numbers of levels even if I think you already have this in mind.

The most important thing: do not explain how to pass the levels. Figuring out how to kill the bosses it is a real fun!

I'm sorry if I didn't say too much about this demo but I'm not english and my brain's fainted due to the various think-translate-write down ^_^°

However I really wanted to say something because I enjoied the play. Continue your work on this way and I'm sure you'll going to give us a really nice game!

Good Luck!
