The fact that sometimes you fall through the ground somewhat forbids any kind of game experience. There is no possibility of methodically exploring the labyrinth, thus making this a "walk around randomly while enjoying the atmosphere and the scenery kind of game". The problem is that there is no scenery and little atmosphere, due to the repetitiveness of everything and the harmlessness of monsters. All in all, I think it needs a lot more work.
Was this inspired by a Lands of Lore game? Felt like LoL2 in my opinion. Because of the music, perhaps.
Best of luck with your projects.
