"Darksy's Adventure" is a consolesque low poly low quality third person action platformer where you control some animal thing and jump around some really poor low poly environments. I think you'd be better off paying for Spyro or one of the console ported platformers that has a lot more polish and quality than this.

This features fairly low quality low poly 3D visuals which will deter a lot of gamers, understandably. Gaming is a visual medium, and it's clear the developers behind this didn't understand that.

Not every "free" game really is. There's often MTX, or content locked behind DLC, or donations being requested, or any other number of things that could mislead gamers, but in this case I'm glad to say this really does appear to be a fully free game.

Nothing demonstrates a developers belief in themselves and their work than giving it away without any remuneration. This is a service to themselves, and the gaming industry, and should be applauded. Of course, just because something is free, doesn't necessarily mean it's valuable.

Even though this is "free", it failed to appeal to the 120 million+ gamers on Steam. SteamDB showed the game peaked at only 6 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.
