The idea was pretty cool, would it prob would need some work on the user interface

- There needs to be some sort of emphasis when something is done.
Example: If a door is open, the camera could temporary shift to it in order to grab attention on what was done. If the object was closer, then perhaps some sort of indicator would do as well.
This way, it would capture the user's attention on what they have done, which tends to be very important in puzzle-platformer games.

Having something to indicate that it is currently loading to the next level at the end of the stage; I always kept thinking some kind of bug was going on at the end of the stage.
(Or more it slightly more obvious if already shown)

Also, there was a massive lag when I first entered stage2, I had to solve it by refreshing the browser, but maybe look into it?
