Pretty nice level. It is fairly difficult to determine where B will land but he rarely gets stuck. It is a fun level. No spectacular tricks and not very difficult.
Funny, I actually won using R as that is what I thought was intended. My suggestion was to allow R to walk all the way around the sliding puzzle area (just in case a player would miss bumping him on to the sliding puzzle.) I liked this level because it was good clean fun. Thanks for sharing!
