Summary: Not many games - ever - really go for something that no-one has ever done before. Most are generic at worst and eclectic at best. How many have you ever played that really challenged the way you thought about gameplay in general ? Lemmings (PC) for sure. Mercenary (Commodore 64/Atari) maybe. Portal (PC) definitely. This is a bold shout - the game is a very short at two hours for a novice player but there is certainly something going on here. I'm just not sure what.
