To note, you don't mention F to Interact in the description of the game. Was a little lost at the start not knowing how to open the door...
Otherwise, things being unfinished is understandable for a game jam!
For a first build, this seems pretty promising. I like that catwalk level right before the ending, and the view outside the window of the intro is pretty neat.
I would suggest a way to make it easier to change from walking to shooting, as it takes a couple taps to switch around in this build.
Nice work regardless!
