I don't want to sound rude or mean, but this game is basically a rehash of an older game called "ENTITY ROOM" (by Gemezl).
I would probably have rated this 5/5 if it wasn't for that.
But, considering that this is basically an unofficial remake, I was left feeling a bit disappointed about the fact that this game really doesn't add much to be considered a substantial improvement over the material is based upon.
I'll give this 3/5.
