Some paid games use drm which needs gplay services to function.

MicroG is what probably is making it work for you. However not everyone uses microG.

That’s a bit sad to hear, but it’s understandable. I guess the only thing that would have been nice was more communication from the devs/moderators.

Thank you for the suggestions! I’ll look into them. Do you know any similar projects to Akkoma? Because Firefish never had any well working Android apps and using something related to Mastodon might work better with them?
