The value story

It has never been cheaper than $5.99. That was January 2016. It has been discounted 84 times in the 12 years tracked here, typically at 50 percent off, with about 6 weeks between sales.

On value it sits in the top 18 percent of its genre. It is pricier than 78 percent of its genre, and better reviewed than 74 percent. Among the games that feel like it, Hob ($19.99, scores 62) beats it on value, while it beats KAKU: Ancient Seal ($24.99, scores 44).

This site sampled 402 of its Steam-purchase reviews; none were written by buyers who refunded it, sampled from reviews written March 2020 to September 2026. Inside the two-hour refund window, 62 percent of the 184 reviews written there were positive, against 80 percent overall, and those are 14 percent of everything written about it.

Valve rates it Steam Deck Verified, and at 9.4 hours it is short enough to finish on one.

What players say

Kind of basic as far as action adventure games go, feels like a Zelda clone. I recommend buying on sale if you're curious as it's a mobile game ported to PC and it shows throughout the gameplay. Negatives: travelling between islands is dragged out (maybe to allow older phones more time to load the maps?), boss fights get more boring as you progress in the game.
MAG_LAZERNot recommendedafter 13hJul 2026Read on Steam
If I had known this was a port of a mobile game, I would've avoided it. While it's not a bad game exactly... It's like an attempt to make a game like Legend of Zelda: Wind Waker, but for iOS devices circa 2012. This game is extremely simplistic. Unlike Zelda games, you don't really get any items or gadgets that give you new ways to interact with the world. You get one: a pair of boots that let you hop over small...
OuroborosChokedNot recommendedafter 25hMay 2026Read on Steam
Awesome fantasy/sci-fi adventure game reminiscent of LoZ Wind Waker and Phantom Hourglass. You can tell that it was made for the smartphone, but it plays much better than you think it would for a smartphone game from its release time. Looking forward to playing the sequel out now and the 3rd game that will probably come out on PC within the next 1-2 years at the time of writing this review.
