Download the demo and try it. It is based off Pacman CE, rather than the original Pacman. This means that, what they did, was they pushed Pacman even further in the CE direction. It is a pure, unadulerated scoring rush, where they take all the stuff that you liked in Pacman, and threw out the difficulty. In this, the goal is to score as many points as you can, by optimally navigating the maze, rather than just eat all the dots and get to the next level. The challenge is now just against the clock, to beat your time, or complete goals. In this, you will build up an absurdly long conga line of ghosts that follow you that you then turn the tables on. It is ghosts overload. Oh, did I mention some ghosts also carry power pellets with them? Yep, they do, so you can wolf down over 30 ghosts in one single power pellet run and keep the scorefest going.
Anyhow, if you want Pacman in a new direction, try it. If you want it to be true to the original formula, you may be disappointed. Is it worth getting 10/10s? Nope. But it is worth a download. I know people are saying they find it really addictive. I am disappointed it looks like they got rid of the weekly leaderboards. I wanted to be able to run one of the CADERS Weekly Challenge.
I do consider Pacman CE a true successor to the original Pacman. I just wish it had a normal mode, rather than timed.
