Picked this up during Summer Sale, kept it in inventory at the time because I didn't know if I'd get around to playing it. Of course, then along comes the Humble Bandai Namco Bundle and all of a sudden I have an extra copy floating around...

This game should carry an addition warning.
The train of ghosts mechanic makes it unlike any other Pac Man (original Championship edition included) but it's just insane amounts of fun in it's own right.
Easy to pick up so it's perfect for the occasional casual bout, but trickier to master than it first seems - so plenty to do if you're a hardcore leaderboard chaser. (Just ignore the top 50 or so on the leaderboards. Stupid hackers stinking things up :( )
