As someone who's doing an internship in a tech company, I can confirm that this is what I go through everyday.
One of the things that can be improved is the feedback of attacks. It's not always easy to tell if your attacks are hitting, and having some visual/sound effects when it does hit will help a lot with the impact. Also, I can't tell the differences between the attacks. Is there a reason not to equip the newest hat?
Other than that, I think it's a short and creative game. Great job on it!
