I have my suggestions!
1- You can make this game with better textures. The characters and accessuaries are looking very low resolotion. If you re-draw all the things, it would be much better!
2- There is no keyboard function settings, you can add that too thats very needed.
3- As optional for server settings, we also should play with the voice chat and you need a report system for the people who are abusing the system. We tired of using Discord or something to play it with more fun.
4- You can add missions like the other online games. Like "complete the cable task 5 times". You can add a level system from it and add some prizes for like each 5 levels thats up to you!
5- You definatly should make a better menus cuz it really is hard to learn how to join a server or other things.
Hope you read all the suggestions and make our favorite game better!
