Very tricky but enjoyable little puzzle. Even when I don't like Spoiler ToA, it was an easy beginning. The way back from the lower level was veeery tricky. The stacking was easy and the last step was tricky again. Had a lot of fun with that!
I agree with @R 'oland but I drop a star because in my case the last step was too unstable...Thanks for sharing @Aris Yn
@ridgerunner I didn't used autopilot. ToA once and for getting back from the lower level to the ground level another crazy move (which I don't know what they call it here).
@R 'oland - Pillar jump move - seems to be the new trending move along with auto pilot SBS (inset stairs under).
