The game is mostly sokoban with 3d rotation of irregular shapes. The special mechanics aren't used as much, and most puzzles boils down to just pushing the block in specific ways, rather than to figure out creative solutions to include the special mechanics. If you were looking forward to the crazy mechanics and their intertwining systems, you will be disappointed here. (Can of wormhole is better for that purpose)

It's not difficult once you realised that. Just a lot of trial and error until you figured out where to push the pipes and place them in which 3d orientations. Some puzzles requires very specific movement with exactly enough space to push things through, most are quite lenient.

5 hours of gameplay, watched guide to figure out the steps along the way. There are 2 more bonus area full with puzzles left for me. Regardless, it's a pretty cool game.
