Wow, this was incredibly immersive! The Zero-G movement feels as smooth as in Prey, and the 'living planet' concept is terrifyingly beautiful. I was particularly blown away by the sound design—the muffled vacuum effect, where sounds feel like they are vibrating through the suit rather than air, added a massive layer of realism. The tactile reload mechanic for the rifle also felt very satisfying.
My only real critique is the intro text: it moves a bit too fast to read comfortably. I’d suggest allowing the player to advance the text manually with a keypress. Aside from that, the transition from the ship to the organic 'fleshy' interior of the planet was a masterclass in atmospheric horror. Great job!
