You should consider having some sort of networking system for multi-player games. Most people use the Steam API to bypass port-forwarding. This sort of thing is very important to have. Also, I would advise not having a 0 dollar publishing fee. This would increase the quality of games on the marketplace. Otherwise, you have to pay a lot more for storage of games that are low quality and that no one really wants to play. This would also be more appealing to bigger budget games because they wouldn't have to deal with marketing in a store flooded with bad games.
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.
