Excellent game, shame most people can't read...
As emotionally stressing pressing the up button is, I think after a while, it should grow on you. I've worked for years just learning how to push the up button, just so I can play excellent games like these. A shame most people aren't as good at pushing the up button as I am, because they can't seem to get the hang of it.
More precise instructions on how to play the game for the idiots:
1. Look at the keyboard
2. Look under the shift key
3. There should be an arrow pointing upwards
4. Press that button
5. Your paddle should swap sides, no more ball magically disappearing!
Really, it isn't rocket science...
Excellent game you have here, one of my favorites. Unlocked two of the mini games so far, hoping to unlock the third. Will be playing for a while!
