I was playing the One Player mode (ball speed never changes, computer moves slightly faster, not sure it's possible to beat it), and then suddenly there was another set of pads and another ball. Something broken there.
Um... should I mention that I still managed to cheat? Not sure what can be done about that. I right clicked below the game, so the menu overlapped the green area, then moved the cursor up the menu (where I could see it) then over onto the green... as I said, not sure if anything can be done to get around that (note: I know nothing about the programming, so might be a simple fix).
Rather slippy surfaces can get rather annoying when trying for a more controlled jump. And given that each level has three lives and you can retry levels... what is the point of the three lives as opposed to just restarting the level continually?
(And not sure what level 15 was about.)
Could use a little more work. Also tighter code, in that I managed to break through the puzzles to get the keys. Otherwise interesting in its simplicity!
