I've been discovering recently how convenient Discord can make developing with the feedback of your community, or of selected members of your community.
This is assuming that you are already talking with your dev team and community on Discord and have a server for that.
Create your game on the Discord platform (they do the same thing as Steam basically), and integrate an alpha-access store page right into your Discord server as a channel. This store page can be restricted to whomever you want via normal Discord permissions. Binaries can be distributed wonderfully simply this way, becuase if you're talking with the community in Discord already, you can just send them to that store page channel embedded directly in your server where they can simply click "install" to test your most recent binaries.
The agreement with Discord restricts only a few things that I wasn't interested in anyway: They don't want you to do an exclusive deal with another distribution service (duh), and anywhere you advertise your game you must mention that it's also available on Discord in addition to wherever else you're distributing it. That's pretty much fine with me.
Anyway, I'm having a lot more fun with this than I had previously trying to distribute pre-release alpha binaries, so I wanted to see what you all thought about it. And what criticisms there are to be had.
