Oh, this is an amazing game. I'm impressed with your time management in running this project. Even though you didn't do everything yourself, using existing resources to create a quality work like your game is not easy at all. Your work has opened my mind about the limitations of solo projects.
I think it would be very useful if you made a Devlog video showing your management process and decisions about which elements to polish. I think developers would find it helpful.
The game is fun!
