Good golly those final few puzzles are so so so dang hard, but after about two-three hours I got it, no hints or walkthrough needed, just lots of head scratching! Amazing game, the puzzles are so well made and I was really pleasantly surprised by the metroidvania element. The hardest part was getting my head around what could and couldn't be rolled / pushed on, a block being sunk into a hole = smooth but a pillar or rock being sunk = rough did my head in, not to mention sinking rocks to then recover wet logs. All very innovative stuff but with so many rules I often got stuck because I didn't fully understand them. The complicated rule set made for some cool moments but I also felt like there needed to be more puzzles to smoothly introduce you to everything. Still loved the game, a real head scratcher!
