Almost too unstable for general release but oddly i liked that. One recalcitrant piece could be tickled into action and similarly , another budgeable usually needed encouragement to fall correctly. I liked the fist move , though initially i mistakenly thought it too was a malfunction. I really liked the almost copycat move and the path that was hard to see.
Very enjoyable puzzle. I did not have any problems with instabilities but the final step took me a while to figure out.
