"FLS" is a rather poorly made 3D "sci fi racing sandbox", and here's a useful thing to know about game development. When developers say "sandbox" they mean "we don't know how to create meaningful content so we're not going to bother". It's like a "Get out of jail free" card for developers who are too lazy/untalented to create content. You just say it's a sandbox and wait for the money to flood in.

Anyway this is a really poor minimum viable product kind of game that seems to have been abandoned. All you do is fly through rings. Like a lame 3D version of Super Hexagon.

The graphics in this game are passable, but could be better. And while it's vital for any game to have impressive visuals (gaming is a visual medium, after all), there's more to a game than just the graphics. To be worth a gamers time, the game must match top tier visuals with top tier gameplay, and that's not happening here.

It's free... now, but it wasn't before. The developer was charging $10 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.

Even though this is "free", it failed to appeal to the 120 million+ gamers on Steam. SteamDB showed the game peaked at only 4 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.
