Ok. So I didn't put the story in because all it is for now is a demo. And the sand was to find press a pressure plate to find a secret key. And I will make those fixes in the full version. I only have this to see how people like it.
And the trials aren't supposed to be long. Because they are only just the first little bit of the map. The rest of it will be WAY longer.
P.S. Thanks for even trying it in the first place!
