As I'm going through my list of never played steam games, I found this one that has 46 reviews, 100% positive.

It plays like a short story about space travel, alien civilization and time loop. The story is okay but what really makes it great is the retrofuturistic frenchpunk atmosphere (takes place in 1975, De Gaulle is immortal thanks to alien octopus cells and you can bribe guards to ancient ruins with pastis). Story, UI and overall gameplay are really cool for a small game.

I had some minor issues with text not being displayed properly, I don't think the game is supported anymore and apparently the team behind it never made anything else. Just like the protagonist I felt like I was discovering some forgotten artifact, except it was released only last year :D

Finished it in less than 4 hours and had a great time overall.
