“I'm not a huge fan of Sokoban, but I have to admit that Isles of Sea and Sky was a lot of fun! I completed the base game almost entirely on my own, except for a couple of rooms and a few hidden gems. The experience was…”
“Absolutely incredible and extremely creative game. Sokovania I'd call it. Everything visual, no text, yet so rich with puzzles, riddles and cool mechanics. Rose up to top 2 meta puzzle / riddle games right behind la…”
“Excellent sokoban/exploration game. Not all puzzles can be solved on first encounter, since some depend on upgrades/unlocks. So if you feel stuck explore some more. The main quest, collecting the stars and gems, was…”

“Incredibly solid puzzle world, like sokoban and Link's Awakening had a baby. Has a whole extra tier of content in the post-game that I just... it's great stuff but it's beyond where I enjoy myself and where I set it…”
“It’s hard and it’s sweet like a riddle in the rain, You win a little wisdom, you lose a little time in the pain. You wander and you wonder, yeah, you circle the flame, Spend hours knockin’ on doors with an elementals'…”
“This game rules. Challenging puzzles, creative mechanics, clever secrets. Just lets you loose and doesn't hold your hand.”

“It's one of those games with a main menu intro that will set the tone immediately. The music is probably the highlight of the game considering you'll be hearing it a lot. The puzzles are mind-bendy but are (mostly)…”
“Just an incredible game. A work of love too. Exploration, presentation, puzzles, gameplay, it hits on every front.”

“So i am a huge strategy and puzzle lover, and when i first found this on my Steam page, i was immediatly intrigued, so i gave it a shot. I do not regret my decisions. The artstyle was super fun, the gameplay is tough…”

“omg I love open world exploration + unlocking abilities + finding secrets! I thought I would feel frustrated and dumb (it is true sometimes), but I actually managed to solve quite a few puzzle and feel smart every time…”
“Incredible game. The elevator pitch: a non-linear sokoban game with a focus on exploration. There is one thing that stands out as a possible deterrent for someone who otherwise likes the elevator pitch; you do need to…”
“Fun sokobanish puzzler! For the most part the puzzles aren't TOO hard, but they are tricky enough to be engaging and it feels fun to solve em. Now these post-update puzzles....they're kinda bastards (good way). Also…”

“in theory i wouldve liked this game but playing a sokoban game where 3/4 of the puzzles available are unsolvable due to invisible elements missing from the puzzle is ridiculously frustrating and just not that fun”

“I'd like to issue a personal apology to this game. It absolutely rules! Some personal history below (feel free to tldr): I'm a Puzzle Freak and backed this game, was looking forward to it like crazy, loved the demo. When the full game came out I played 10 hours but totally…”
— a player, Steam review · 38 hrs played“Think "Legend of Zelda" meets "La Mulana", with a dash of Sokoban, The Witness and hidden-object puzzle, and you've pretty much got this game. It's an easy enough game to get into at first, but once you start getting into the later stages, you'll be thankful for the Community…”
— a player, Steam review · 24 hrs played“Starts awesome, but eventually became disappointing to me. The first few hours of this game are bliss - you are discovering one thing after another. The puzzles are small and contained, and it's generally clear where the next puzzle is. Some puzzles are too hard and you can come…”
