erm yes i know but the maximum number of players cant be rised because of this reasons: 1. The Game is beeing hosted on Silverlan's(The Developer) Laptop so if u arleady have noticed more slots would cause more laags and higher ping(full server is also laaging everyone has nearly a ping of 150 or more if there are only 3 players u have a ping of 70...)
If u ask why this is the reason: To prevent people stealing Silverlans gamemode, the only way you could help getting up a server would be if you send him money for a gaming server.
2. The map isnt that much Big so if there are More players everyone would have problems with too less npcs and so on
3. I think if the Gamemode is in beta or at the final version there is going to be a more slotted server but this will take a while this is still a pre alpha
