Well you could try to make a more complex game. For example adding more obstacles or moves etc. To improve the graphics you can just practice drawing or ask a person that has better drawing skills to help. Also sorry if I was too harsh.
No problem dude sometimes people need to be harsh and you're right about the obstacles I just really couldn't think of anything gameplay wise the entire game was based around the idea of the mc rushing to adulthood hitting it hard and wishing he could go back
