Custom Bitmaps?

[Otrebor671]

Hello, thanks for your great work. I am able to run it on the ESP32. It's not an issue, but I wonder if you know a way to customize the ROM bitmaps to display a custom character on the screen.

Also, I would like to know if there is a way to manually handle or modify character parameters in order to implement new mechanics for leveling up or other interactions, to avoid classic feeding or playing methods.
