The pixel art looks good. The ambient music is nice but maybe a bit too chill for the story...
I found myself skipping dialogue because it was repeating in a row. It may be a good idea to disable the intro dialogue interaction listener after the player goes through it once.
The key in the dungeon should disappear similar to the floppy disks. It was confusing if the character took it or not especially since there is no inventory.
The walk cycle is rubbish - it looks like the character is bending the knees in the wrong direction... Needs to be redone. Apologies for being so direct.
I chose the ending where I reset the computer. Nothing happened then - just returned to the main menu. That's anticlimactic. I guess you didn't have time for the jam and you are going to make it more interesting after.
I'm curious to see what happens with the other ending.
This game has potential to expand. Good luck!
