This is a pretty fun game! Since it's not in active development, would you be willing to release the source code/files?
What do ya think about, aside from releasing the source code, also opening a donate link? I know that it's something on itch.io, but, if you do release the source code on a platform like, say, github, it'd be nice to drop a "buy me coffee" or "buy me a beer" link. Hell, maybe that could help ya with your current project.
