I realized the moment I fell into that fissure...
Uh, decent game but the only thing that really stood out--to me--was the striking resemblance your dungeon theme had to one of the songs from the game Myst. In fact, I might say that it is exactly the same. Did you guys get the license to use it? =.=
Anyway:
+5 for decent overall design.
+1 for decent art direction.
-1 for repetitiveness.
