What I liked:
Very inventive concept and use of the theme. The idea of weaponizing claustrophobia when the topic is space is inspired!
Aesthetics are strong. The droning music and choice of color palette definitely work to set the ominous tone you're going for.
The tuning of how the walls react to the flashlight are well done. While I was always sweating keeping the walls away I never felt like it was impossible.
What could be better:
In addition to the movespeed bug, using a controller caused a number of glitches. I was unable to go down the first hatch and had to restart, and while I was able to use the keyboard to continue on my second playthrough as soon as I tried using a controller again all the other controls and the exit to levels stopped working.
I didn't feel like I was making any interesting or informed decisions while walking around the rooms looking for the exit. With its location being a shot in the dark, levels can become tedious rather than scary if the player picks the wrong direction to go through no fault of their own. Perhaps some other horror element could try to scare the player in the correct direction? Follow the screams as they get louder towards the exit hatch, perhaps?
