Cute game! The wall jump worked really well (I hope that wasn't too hard) and the dialog was fun. The difficulty and length were just right for a game jam, too. Two suggestions:
1. I did sometimes have trouble getting the dialog to open. Maybe you could make it more forgiving?
2. The guy who opens the door continues to say "get me the codes and I'll open the door" even after you've already done so (and he's already done so). Would be nice to change his dialog at that point.
Overall though a fun game. Well done!
