Level select didn't work for me... so I had to play it all again :( Besides that... great game. Had even more fun after I've read what the game was about originally.
Ok, so maybe I found a bug. I have to rescue that scarf guy. I looked it up in the walkthrough... but I can't use the control panel to switch the direction of the conveyor belt (with the big guy). It's getting to 'Flip the switch - yes", then it just says "The switch is unresponsive".
