I wouldn't be surprised. I've bought your games and flat forgotten about them because of life until I check my Twitter timeline and get reminded. (why am I checking twitter this late in my timezone though?)
interesting thing: less than the 10-12% of people who bought my games on itch.io in the recent sale redeemed a Steam key. Maybe they're busy playing other games and forgot though

Thanks. Twitter will use this to make your timeline better. UndoUndo

It's probably because it not that obvious how to actually get the key. If you buy in the app you then have to go to the download page in a web browser to get it.

ah OK didn't know (I never tried the process myself as user)

I'm guessing that those who buy on itch.io don't want to play on Steam. XD

well might also be that right now they're swamped with games and they'll get back to them later :P
