First of all apologies, the game is not got a name yet, it is at the moment a tech demo. However, this is a tech demo wich shows what can be potentially a brilliant puzzle game.

In some way it reminds me about Perspective (another very good game, and it is free) in that it is playing on forced perspectives, but this is in first person and not as straightforward.

This is something worth following to see what it will end up as, and as long as we have students with an imagination like this coming up, I do not fear that the game industry will stagnate :)

Take a look at the tech demo:
