Cool game and cool interpretation of the theme! I wish I could finish it but it seems like the door code isn't working for me? I'll come back and finish it if I'm able to!
The control scheme probably should have been simplified imo. Enter and spacebar could be one button, and honestly the combat could also be enter/spacebar, with you hitting in different directions based on the direction you're facing.
Overall a great entry! I can't believe this is your first game jam! Great job!
