It's a pretty fun idea and the game looks good, but I'm missing some player feedback.
For one it's a shame there's no sound effects for deaths and fire and such, and some things are a bit surprising. In the last level for example I was certain I had to do something with those two mushrooms, and the little rock on the ledge that turned out to be a bomb was a nasty surprise.
The game also controls a little too sluggish imo. Making all the characters just a little faster would be better I believe. All in all fun concept, but it needs a little more meat on its bones (and a spelling check. A few hints such as "princess" vs "prince" are confusing and the game page says skills are used with E while the game itself says right mouse button).
