SHINAN'S PROFILE

One idea could be to do both. Steam is not the discoverability machine it once was so I think Cash is right that putting it out in as many places as possible is probably the best bet. And you can always make it commercial in some places and less so in other.

Let's say you put a 5€ pricetag on it on steam. Then you have it on Itch.io with a pay what you want model (with a recommended price of 5€). That could be a way to keep the "prestige" of a commercial game but the availability of a free one.

I think, though this is just speculation, that having a free game of steam is probably not too great for discoverability, since having a price tag means you can discount it and then it will show up in sales lists. While a free game will never do that.

They are not automatically saved. You have to do it manually by pressing the submit button. (if the mandatory screenshots are not there it won't show up in the submission queue, so you can continue to work on it later)

The only bad sign is that maybe it will be delayed into 2021!

EDIT:
The Final Fantasy 7 remake also got delayed and that one I do hope is a sign of bad things to come :P
