Wow this game is really excellent! It might be my favorite, at least out of the games I've looked at so far.
The atmosphere and sound works very well, and the game just has a lot of vibes. I see I'm not the only person to comment "yo this game reminds me of <thing>" but for me it makes me think of SCP and Superliminal. And I figure you're doing something right if the game evokes things for people :P
And the core mesh-dilation mechanic is both pretty cool and highly theme-relevant.
One thing is the cursor stayed visible for me and I could see it jittering around weirdly as the script forced it to stay in the center for the first-person controls. I'm 99% sure this only happened because I was playing in browser though, and the page does say it looks better if you download the game. Sadly I'm on mac so it was the only option for me. But I'll assume most people didn't have this issue.
Really nice work with this one.
