and used most of it on my game
You seem to draw your assets yourself. And do all the other things. What did you spend it on? If you just spent it on living expenses, that does not count as having it invested in the game. You are not a professional coder that could have spent the time freelancing. Nor are you the kind of artist that does commissions. So you are not "hiring" yourself.
Also, your game does not work. It's just a black screen with music. A little yellow thing on the top.
I suggest you join a few game jams and try making small functional games as per rules of the respective jam. Try out the craft of game making. You might be an artist, but would you think the singer of the soundtrack of movie would be qualified to direct a movie, just because that singer is an artist?
