Thanks to get in touch with us and for all the advice. :)
For multiplayer, yes but not at the moment. Because we are still developing several functionalities for both website and the desktop app.
About 0 dollar publishing fee. Right, but as a new and small webplatform we can't be so restrictive, at least at the beginning. So we don't want to charge developers to publish with us, at the beginning at least.
About game quality, well, this is crucial for us. First we won't publish everything. In addition, for everyone who wants to publish through our marketplace, devs need to implement a small simple piece of code we provide for language and major game engines. This is for copy protection, and it is during this process that we will test games and eventually decide to unpublish some of those.
Our criteria is flexible, but of course we don't want to have trash games, otherwise the platform won't be attractive for gamers.
