Knock Harder

You are inside a multi-level dream. No one knows when it is over and you wake up in reality. Observe your surroundings and inspect everything. All around you is just a dream if you spot something strange. This is the only way to wake up. If you think that everything around you is the reality then try to survive until the time-out. However, if it's timeout inside a dream then you will die in reality.

The goal of the game is to reach reality. You must be careful. Any awakening can be the final one inside reality. Don't get yourself killed in there.
