The orb under the stairs was a little hard to find.  For as bright as they look, when you see them, it might have been nice for that one to have some visible glow to indicate that it was there.  Also, I never needed to use the Teleport skill, since pushing the boxes up the hills allowed me to escape the rooms.  Because of that, it would have been nicer if the boxes were easier to push.

I'm also not sure what the purpose of the pit under the boardwalk was.  I fell down there and got stuck and had to exit the game because there was no way out.  The deforming terrain was an interesting idea, but it didn't really go anywhere.  It would have been nice to see that developed further.

I think this was a good start for a game.  If you had more than a month, I think you could do some interesting things with the premise.

Good game! I miss some music or ambient sound.
