This is one of those gems that can be done in minutes.
The perfect game when you want a short sharp IF experience.
If you're looking for a deep story line this isn't for you.
If you are looking for a quick clever game, then yep look no look further.
Of course you could be one of those people that solve it in a flash, which is unfortunate, because the fun is then lost.
Should take anywhere from 2 to 10mins or so.
Great game, Loved it.
