Hi Vasileios, thanks again for the review! I consider publishing my android games here as well, but up until now I had a couple of reasons why I did not do it.
The play store might not be the most friendly platform, but updating new versions is really effective there. In the first months I had biweekly new features, and could be sure that all of the players had the latest version real quick.
Having all the statistics in one place is also a benefit, but I guess my main reason was that I still don't trust itch.io as much as the play store, and I fear that uploading an apk here will result in uncontrolled copies.
I admit I did not do any research in this topic, and will do that in the near future.
