I’m just gonna say it. Most "open world" games are lying to you. You spend half your time following a glowing dotted line or clearing out icons on a map that feel more like chores than actual discovery. But then something like Isle of Sea and Sky comes along and reminds you that exploration should feel a little dangerous for your brain.
It's a sokoban game. Sorta.
Actually, calling it a sokoban is like calling a hurricane a "bit of wind." Developed by Cicada Games (primarily the work of Nathan Oneday), this thing is a massive, sprawling, non-linear epic that feels like someone took the DNA of The Legend of Zelda and spliced it with the most devious block-pushing puzzles ever conceived. You wake up on a beach. No tutorial. No hand-holding. Just you, some blocks, and a world that expects you to be smart enough to keep up.
The Mystery of the Archipelago
The game doesn't waste your time with a twenty-minute cutscene about ancient prophecies. You're a character named Kelp. You're on a quest to find some Great Spirits. That's basically the gist, but the narrative isn't the point; the vibe is. It captures that specific 8-bit aesthetic—think Game Boy Color—but expands it into a world that feels infinite.
There are over 3000 screens.
Read that again. Three thousand. In a genre where most games give you 50 to 100 hand-crafted levels, this scale is honestly absurd. You’ll be wandering through a lush forest one minute and then, through some clever block-shoving, you find yourself in an underwater cavern or a desert filled with heat-sensitive mechanics.
The coolest part? You aren't locked into a linear path. If a puzzle feels like it's melting your synapses, you can literally just walk away. Go east. Go north. Find another island. You might find an item or a new mechanic elsewhere that suddenly makes that "impossible" puzzle back home look like child's play. It’s a very specific kind of freedom that most puzzle games are too scared to offer because they want to control your "learning curve." Nathan Oneday clearly trusts the player more than that.

Why the "Open World" Tag Actually Matters
Usually, "open world" means a big map with nothing to do. Here, the world is the puzzle. Isle of Sea and Sky uses a "metroid-brain-ia" approach. You don't necessarily get a double jump or a hookshot to progress (though there are collectible items that change how you interact with the environment). Instead, you gain knowledge.
You might see a weirdly colored block and have no clue what it does. Two hours later, on a completely different island, you learn how that block reacts to water. Suddenly, your brain flashes back to that first island. Oh. I get it now. That "Aha!" moment is the currency of the game.
Mechanics that shouldn't work (but do)
- Environmental Storytelling: You find tablets. You see ruins. It’s subtle.
- The Day/Night Cycle: It isn't just for show. Some things change based on the light.
- Key Items: You find things like the "Pearl" or the "Flute" which aren't just keys for doors—they are tools that fundamentally break your current understanding of the movement rules.
Honestly, the movement feels incredibly tight. For a game where one wrong push can "ruin" a puzzle, the undo button is your best friend. And thank god it's instant. There is no penalty for failure, which encourages the kind of "what if I try this?" experimentation that makes the genre fun.
The Difficulty Curve is a Jagged Mountain
Don't go in expecting a cozy, breezy afternoon. Isle of Sea and Sky starts out deceptively simple. You push a block onto a switch. Easy. Then you have to push two blocks. Okay, fine. Then you realize the floor is ice. Then you realize the blocks are sentient. Then you realize the blocks only move when you aren't looking at them.
It scales. Hard.
But it’s fair. Every single time I got stuck, it wasn't because the game was being "cheap." It was because I was stuck in a specific way of thinking. I was trying to solve a 2026 puzzle with a 1990 mindset. The game constantly asks you to unlearn your habits. It’s brilliant, frustrating, and incredibly rewarding.

Comparing it to the Giants
If you loved A Monster's Expedition or Stephen's Sausage Roll, you’re the target audience. However, those games feel very "contained." They are sets of levels. Isle of Sea and Sky feels like a place. It’s more akin to Animal Well in how it treats its map as one giant, interconnected secret.
The music deserves a shoutout too. It's chiptune, yeah, but it's atmospheric. It doesn't get annoying even when you've been staring at the same screen for fifteen minutes trying to figure out how to get a turtle across a pond.
What most reviews get wrong
A lot of people complain that the game is "too big." They say it’s overwhelming. I think they're missing the point. You aren't supposed to "beat" this game in a weekend. It's a slow burn. It's the kind of game you keep on your Steam Deck or laptop and chip away at over months.
It’s about the journey, not the credits.
Real talk on the "Collectibles"
There are these things called "Star Shards." You need them to progress past certain gates. Some people hate gatekeeping, but in a world this big, you need some structure. The shards are hidden everywhere. Some are rewards for tough puzzles, others are just tucked away behind a fake wall you’d only find if you were paying attention to the tile patterns.
It rewards observation. If you’re the type of player who mows through dialogue and skips exploration to get to the "boss," you will hate this. If you’re the type who likes to poke at the edges of a map just to see if the developer hid a secret there... well, you’ve found your new obsession.

How to actually survive the first five hours
Look, you're going to get lost. It's fine.
First off, use the map markers. The game gives you tools to label things you don't understand. Use them. If you see a weird pedestal, mark it. If you see a block you can't move yet, mark it.
Secondly, talk to the NPCs. They aren't just there for flavor. They often drop subtle hints about how the mechanics of a specific biome work. They won't give you the answer, but they'll point you toward the right question.
Third, and this is the most important one: Walk away. The non-linear nature is the game's greatest strength. If a puzzle is making you angry, the game is telling you to go somewhere else. There is always—always—something else you can be doing. You might find a whole new island chain you didn't even know existed just by taking a different path at a crossroads.
Actionable Insights for New Players
- Don't Fear the Undo: Seriously, use it constantly. Experimentation is the only way to learn the hidden "rules" of the objects.
- Look for Patterns: The art style is deliberate. If a tile looks slightly off-color or a patch of grass is missing, there's usually a reason for it.
- Check Your Inventory: Sometimes you'll pick up an item and forget it has a passive effect. Read the descriptions.
- Prioritize the "Main" Spirits: If you feel aimless, try to head toward the larger icons on the map. They usually house the "major" puzzles that introduce the big new mechanics.
- Take Breaks: Your brain actually processes puzzle logic while you sleep. I can't count how many times I've woken up and realized the solution to a puzzle I struggled with the night before.
Isle of Sea and Sky is a rare gem in a sea of generic "puzzles." It’s ambitious, it’s massive, and it doesn't care if you find it difficult. It respects your intelligence enough to let you get lost, and that’s exactly why it’s worth playing. If you want a game that stays with you long after you turn off the screen, this is it. Go get lost. Find the spirits. Just don't blame me when you start seeing block-pushing puzzles in your dreams.
