Has potential
I can see some potential, but as already said, the lack of sound effects at this point was a bit odd. There were also a fair number of invisible barriers, I don't know if that was intended or not but it was a little frustrating having to go back to drop down a level just to walk to the exit. Beyond that, maybe mention that the ice stage is the current end, unless there is indeed a way to get past it, as I kept having to go through it.
