Don't collect the coin left of the yellow button until after you tramp.
Push the cube onto the ice so it bumps the upper cube then step into the TP and wait til they are stopped.
Then tramp R-R-D-L-D then walk up to collect that coin and step on the yellow button.
I had completely forgotten about this level. I had tucked it away in your folder.
Turned out to be easier than I thought. Took me several restarts figuring out the green spheres, the red one sonly took me two restarts, good thing I remembered that little trick from one of your other levels.
Stinky enjoyed taking the path back to get that last coin. Thanks for the fun Kiki.
