And I did enjoy it, Kazza! I'm still unsure about one thing, but was able to make it work. Got all the prisms where they needed to go and got all the coins. First time around, I didn't know I could go home, found it by accident. Knew better the next time.
Victory at last! I didn't think I'd ever get this! And each time, I THOUGHT I'd figured it out, there was something else. My next to the last try, I had it all down, I thought, then discovered there is one little button you must not cover too soon! Finally got it - this was lots of fun to figure out & play. Thanks, Kazza!!
This was one TERRIFIC puzzle, Kaz Thought I knew what needed to be done, but doing it was something else. You're "Not Getting Older (with levels), You're Getting Better". Terrific enjoyment.
This one had me stumped for quite awhile! Finally accidentally figured out something, than iy took me a few more tries to relaize how I had made it happen. DUH!
Finally got it - this was lots of fun to figure out & play. Thanks, Kazza!! 
I fell for every trick you set for us 
Thought I had it - then was one coin short - you know where it was and I couldn't get it!
Finally the penny dropped.
Thanks to Kymmie.
