do indie developers use any kind of analytics software to track their games?
Yes.
Or is it just “vibes”?
That, too. Not everyone looks at analytics.
I check the Dashboard Analytics areas here on itch.io out mainly as a way of checking visibility or out of curiosity.
Tho, in general, I feel descriptive feedback is much more valuable than statistics are. Numbers don’t say why someone visits, plays the game, or downloads (or attempts to) multiple times. Do they enjoy playing it, or do they resent ever learning of the game after dealing with a bunch of crashes that only they experience?
What should I do?
Finish the game first.
