Shift

A clever platform game where the floor is the roof and the inside of blocks is also the outside... Umm... Control the character with the arrow keys and then use the shift key to invert the man about the floor he is currently standing on. Collect keys to open gates and avoid the spikes (both sides of them). There is an in game timer from which you can find your score and plenty of in game text about the in game timer (almost all of which can be completely ignored :-)
