4D Golf is a perfect game for reasons I cannot describe without spoiling much of what makes it so special. If it even remotely interests you, please go play it and play it all the way through.

I will say it is not a particularly hard game, nor is it particularly long. Half the time it was just my (lack of) mini golf skills that really got me in trouble - and the game doesn't really care how many strokes you take. Just beating these levels is the real accomplishment, and you can return for par or better scores later.
