You all have made some great points about this game:
The sounds are terrible. Nothing here sounds like real Pac Man. The "Boo Bee Boo Bee" start noise is off key and just wrong. Turning the sound down and putting on Slayer works better.
The collision detection is off. LOTS of cheap deaths. It removes the "seat of the pants" close calls from the arcade version.
Controls aren't very good. The higher level you go, the worse the controls seem to get.
Brilliant comment on calling this a "Pac Man Clone". That's exactly what it is. Like Munch Man or Cosmic Cruncher....close, but not too close to real Pac Man.
The frustrating part for me is that they could have made it so much better with just a little effort:
Use a black background and blue maze.
Use a cherry instead of the vitamin. Even if the fruit doesn't change...a cherry would have been better.
At least TRY to get the sounds close.
