The game is awesome, but AI ruins it. The ghosts can only kill pacman either accidentally, you can control more than 1 but the one you just controlled will go into a different direction.
The pacman's ai is worse, it's both genius and dumb. It's extremely good at evading your ghost, especially when you are alone, and when you are alone, you can't physically outmaneuver it.
Also, if as single ghost you will go into a specific corner, you will get pacman just circling you, it's AI trying to "evade" you, stuck in a permanent loop.
This 15 year old game needs some polishing
