This release's cube offering is the very tricky and unique "Worm Cube" by Askerli. Each piece features concentric rings on two planes, which makes figuring out what goes where a very tricky endeavor. The level 220.127.116.11.3 solution gives nothing away. I cannot stress enough how confusing and difficult this puzzle is to reassemble. You've been warned!
Construction of this puzzle is superlative, with over 500 bevels on each cube.
