What about something like a seasonal reset? 4 to 12 times a year.
Mandatory battle pass to help keep the lights on.
Solana is a better chain but same problems with extractions from players but more exposure.

Personal mental and physical health has to come first if you are going to keep doing this. Rule number one if you are not enjoying it do not do it.

OSRS has been fighting farming and extractions for over 20 years. RavenQuest is dealing with the same problems as you. Maybe reach out to teams for advice.

Hope you figure it out. Changing and resetting the themes every so often would allow you to keep what works and getting rid of what does not.

P.S. I know nothing about coding.
