Very much inspired by talos principle with a touch of lightmatter and a sprinkling of portal, classic first person puzzle approach. If you love those games, you'll at least like this.
Be wary, it's janky. Performance is bad on good hardware, especially with the portal mechanic active. Graphics are...decently styled, but feel very 1999, and a lot of graphical bugs like one-sided textures and z-fighting.
There's voice acting. It's not great, but the bar has dropped on that recently with a lot of bad voicing coming out, so I would've been more annoyed in 2022 than I am now.
The time-portal mechanic kinda sucks, every game that has tried that type of mechanic (including my beloved talos principle 1) has failed at it, it's best avoided. The other mechanics are good. I like the combination of TP-style gear with LM-style beam width control.
Some puzzles have unused gear, implying multiple solutions are possible.

So, yeah, it's got a lot of problems, but a lot of good too. You'll get your $17 worth of entertainment if you like puzzly games.
