You must be very unhappy about your job, you reflected in on your game :) Joking aside, i like the use of humour in the game. I couldn't see much point in the game. First of all i think you cannot lose the game. You don't have a certain amonut of lives. You die and you respawn again forever, so there's no losing which beats the purpose of any game.
I like the art in the game especially the bosses, they're just idle images but they look cool. Lack of sound is a bummer too. A game needs sound effects.
I think this is your first game and it's really something for the first attempt. It also must be difficult to write this from scratch in Python. My respects for your effort and good luck on your future projects
