Two things to consider:
1. Monetising a hobby can make that hobby into work - draining your motivation to do it.
2. People want to support developers they like but may not want to support a specific game. You might consider a revenue/donation stream that is not linked to a specific game, e.g. a Patreon or alternative channel where those who want to support you regularly can do so.
Good luck!
Thank you for your advice. Both points are valid. To be honest: payments here at itch.io were almost non-existent until I set a price tag. It is the generously support over Patreon that gives me the chance even to consider it.
Also true is the point that work is work. So it won’t be “just” a hobby anymore. Lack of motivation or a just a creative blockade can have a significant impact. Or people simply not liking what I do anymore.
I have been self-employed before and know what it is like not to be able to pay you bills anymore. That’s why I am so hesitant and want to make sure I can sustain myself with this.
