System Requirements
Probably not much. I haven't tested it formally.
Just don't play it on your 8 year old netbook and you should be fine.

Avoid lava. That would be my first tip.
Other than that, just to try to stay out of corners, you don't want to get trapped far from any other platforms around.
The bonus items are good, but if they're a bit far away, they're probably not worth the risk, since you lose all the ones you've saved up if you hit the lava.
