Wake Up Call is a short interactive piece that takes place inside a comatose man's mind. As you are trying to wake up, you can see your mind trying to reconstruct its basic capabilities like spatial reasoning, logic, memory, words or decision making. Your memories will also start to come back to you and maybe, you'll prove you're worthy of earning your consciousness back.
I would call this game rather a interactive piece of art than a game. You control some things, but on the other hand there are the strange effects you are experiencing during the coma. Despite its very short lenght, you should give "Wake Up Call" a chance as long as you have around 20 minutes to spare ;)
