Nice, I got immediate From Dream flashbacks.
It wasn't clear to me that you needed a bullet to heal and I died at the second monster, it respawned me in front of the brainserver and the game broke, it played the brainserver introduction again despite the first enemy being dead, then every time I loaded in the previous area it kept respawning the rope, resetting the computer and the combat encounter.
Restarted and killed the second enemy, this time the game remembered I took the hook rope and that the computer's cipher was solved. Interacting with the computer again makes the second enemy visible but it doesn't reset the combat encounter like in the first playthrough.
Spamming E in the bunny dialogue makes the text appear slightly before the textbox, which isn't a problem but it is odd that they aren't parented.
I still have no idea how to solve a cipher, I just stared at the letters until I kinda spotted a word and guessed it right both times. It's not your fault because it's a hard thing to understand without a clear step by step example but maybe you could replace it with a more easily understandable puzzle.
It's a fun demo, I liked the atmosphere and I'd play more just to see where the story goes.
