I loved the introduction and overall goofy theme. The limitation is well done and I would certainly consider an office building a dungeon lol.
Feedback: Besides getting locked out of the elevator once not very buggy. I am not sure if you had enough time, but I feel like having the charged attack do more damage would feel pretty good. Also increasing enemies health based on their armor and making the shield bash do something.
Overall very well done, keep up the good work!
