Funhouse is one of my absolute favorites. Beside the obvious - friendly Rudy turning narky as it approaches midnight - there's some classic shots on this game. The left outer loop (Gangway) which takes you to the pops, the Hallway entrance, the centre mode start hole which can be made several ways, but my favorite is a slight deflect off the Super Dog targets (billiard style), the right hand loop through the pops which is way harder than you'd expect, and the upper loop off the upper flipper which after three loops gets so fast the ball is flying.
And you get to whack Rudy in the mouth!
Who could ask for more?
