One of the few games I was keeping an eye on is out, so I gave it a look.
Isles of Sea and Sky (formerly known as Akurra) is a Soko Ban-clone with some depth. You push blocks to solve puzzles and progress through a gameworld consisting of a cluster of islands in what appears to be a Polynesian setting with elemental stuff thrown in. There are different kinds of blocks with different properties. Wooden boxes can be smashed if hit hard enough, and fill up holes if pushed into them, gravel can be burrowed through from end to end in a straight line, obsidian blocks can be pushed into lava, etc.
While it's a nice puzzler, it has three big flaws which made me give up playing it:
1) Puzzle fatigue. ~20 years ago I was heavily into the DROD-series (Deadly Rooms of Death), which shares some features with this game. What made me give up was how the DROD-games kept churning out endless amounts of new puzzle elements and enemies as you go through hundreds of puzzle screens per title (only the 2nd game, Journey to Rooted Hold, got the balance right). This game manages to drain me on the first island visited. You have to collect 12 elemental gems, stars, keys, upgrades, find hidden musican notes and look for secret passages, all while trying to solve the puzzles laid out. It came on too heavy, too quick, and I didn't even finish the island before quitting.
2) No motivation. DROD had a (silly) plot and story driving it onward. IoSaS has nothing. You're a guy who washes upon the shore of an island, nothing is told, nothing is shown. There's a girl who keeps teasing you to follow her, but she hasn't said a word yet. So I'm just running around collecting stuff because...?
3) $20 price tag is too high for this one IMO. This is a much smaller game than the price tag suggests.
There used to be a demo for this game available, but I'm not seeing it on the Steam page. If this game interests you, I strongly suggest you look before you buy.
