My game Rhombus just released today, a 1st-person puzzle game with non-linear exploration and metroidbrainia elements, and it has native Linux support.

Hey r/linux_gaming,

I'm Axel, the developer of Rhombus, a compact non-linear 1st person puzzle game built around a unique core mechanic where you build your path by making platforms go up and down by interacting with panels representing these platforms through perspective.

It is about 2-3 hours long and draws inspiration from games such as The Witness (panels), Antichamber and Manifold Garden (visual style) or Leap Year (compact non-linearity). And of course, it has native Linux support.

If it sounds interesting to you, then you can check out [Rhombus on Steam](https://store.steampowered.com/app/3959950/Rhombus/?utm_source=rlinuxgaming).
