Spoiler: Tricks? I don't know if pushing a ball when B is standing on it is considered a trick or not. Thanks to @Ray Aznable for playing the original and finding a minor goof, and thanks to @GFJ for playing the fix and finding a major short cut. The things you don't see...
@delator77 I've never really liked the 'rush hour' / 'traffic jam' puzzles, but I figured it was time that I tried one... this one didn't turn out that well, but what the heck - maybe I'll experiment with it a little.
@GFJ Thanks for finding that shortcut in the previous version - I can't believe that I missed something that obvious.
... my most favorite level from you based on design, and there are 5 type gameplay in each different sections which are easily to be seen and differentiated. good level to learn about movement set divided in different room.
