It’s always a struggle to start something new, but if you want to evolve your project, try using external tools like Piskel (to create your own art, if you can draw) and Photoshop for map editing. Try to create a unique identity for your game that reflects your personality.
Also, learning how to make sprites and using tools to create your own plugins (like VS Code with Copilot) helps a lot. Using AI as an auxiliary tool is fine; it only becomes a problem when you let it do everything for you.
