"流浪荒岛" is a poor quality ripoff of Legend of Zelda with an attempt... and I say "attempt" because it doesn't really work, to add base building and other features that never really panned out. The quality is extremely low, and the game failed to garner any interest from gamers on Steam.

There's no English translation for the game, but that's okay. The language of bad games is universal.

This features really godawful pixelcrap "art" instead of real graphics. It's hard to say if this was because the developer didn't have the skill to do the job of creating 3D visuals, or couldn't afford to hire someone who does, but it also doesn't matter. What matters is that this looks much worse than most other games because of that decision, and that's a major deterrent to gamers. Games like Terraria and Stardew Valley succeeded despite the bad graphics, not because of them.

It's free... now, but it wasn't before. The developer was charging $5 USD for this. Price barriers, especially on low quality products, can be a direct cause of failure. It's a nice gesture for the game to be given away for free, but it also tells us that the game wasn't good enough to succeed as a paid product. It's also a bit of a slap in the face to anyone who paid money for this... nobody got refunded.

Despite having no up-front cost, this failed to appeal to the 120 million+ gamers on Steam. SteamDB showed the game peaked at only 3 concurrent players... this is a dismal public reception. This was so bad they couldn't even give it away.

Bearing in mind that free games don't add +1 to your game collector count, should you bother adding this to your library and downloading it?

Not this time. This isn't worth downloading. While this won't cost you any money, you get what you pay for, and sometimes, even when the game is free, it's still not enough.
