This is a really sexy, cute and charming game (which you don't have to be a furry to enjoy), and its main flaws are in the process of being worked out.
Playing as the survivor of a plane crash on a deserted island, the gameplay combines survival/resource management mechanics with the gradual befriending and seduction of a wild catgirl. You're basically trying to tame a cat who also happens to be a sexy girl. At the same time you're trying to find out if the female pilot also survived the crash.
This "taming" is the heart of the game, and feels quite rewarding. You do have to work for the progress you make, but it's not too tedious, and you get payoffs all along the way. And the effort and the twist and turns of the story succeed in making you bond with the catgirl, so that the connection becomes meaningful.
The graphics are first-rate, and the animations pretty decent (using a combination of frame-by-frame changes and Live2D stretch/bend transformations). The models are hot, and there are a number of nice lewd scenes, all the way to full intercourse. I like that the sex scenes are interactive, though they can be a bit fiddly, so the option to just have them play out (in some cases only available after "winning" them once) is welcome.
In earlier versions, the game suffered from a few problems.
First, the lewd scenes were limited, as you didn't yet get very far with the catgirl. This is no longer an issue.
Second, the mini games for hunting, fishing, learning, etc. were very sluggish on some platforms, making them extremely tedious. This has been greatly improved in the latest version (although the "click the falling objects" mini game is still too time-consuming), and they're now quite playable.
Third, the survival and resource mechanic could get a bit grindy, particularly the first time you play when you haven't figured out the best strategy. On the highest difficulty level it was almost unwinnable at one point. The devs are constantly rebalancing to improve the flow, and I feel it's now fairly forgiving, at least on normal difficulty. (However, it's still annoying how few actions are possible per day. Some more interesting things to do at night, particularly in the early game, might help.)
Finally, the big one: the game communicates entirely in emoji. I don't think the devs fully realize how big of a hurdle this is for many players. (Replaying it, with advance knowledge of what the game is trying to convey at each point, is a totally different, much smoother experience.) If you're not fluent in emoji as well as the custom grammar and symbols invented for the game, even the simplest sentence becomes a riddle to interpret, and you end up spending more time and mental energy solving rebuses than actually playing. It's also very easy to miss some instruction or hint because you don't understand what the game is saying, or because you were tired of decoding the messages and skipped past some line of visual gobbledygook.
Thankfully they are now reportedly testing a version with English text, and at that point this should be an easy recommend to all players.
