This was excellent! Loved the twisting and turning of the space. The way you end up walking on what used to be the walls and ceiling feels surprisingly natural.
Given that mechanic and the limited colour pallet, you’ve done a great job making it readable. I only felt a little lost at the end, once I had both keycards, but forgot where the controls were.
Also loved the boot up screen with all the old sounds! (Great to see the land traditional owner acknowledgement too. I used to live in Australia.)
