I got it. I was diverting the UFO so that it went into the other room down there, so I guess that was a big no-no as I soon found out.
In the metal box room about every other time I'd push that last keg into the red tp only to have it just explode without blowing up the box. In the keg room I forgot to get my stinker out of harm's way when the UFO blew up the other keg on the timer. Then in the goob room I went right instead of left.
In the sphere room I made it across the first time then the next time I realized what the conveyor button was for...duh
In the prism room I kept messing up the tramps, I couldn't figure out why I had to go up when I just really wanted to go right to the exit. But I got it. great level here Bob, I enjoyed it. Thanks for the fun.
BTW-your avatar is really freaking me out. Looks like Santa's been drunk and derilect....the big dude.
