So, this game is most certainly not dead, but I have decided that multiplayer is a requirement for it. So I started a new designing the engine from the ground up to make online multiplayer possible. This is the first time I've ever done anything like this, but it seems to be going well. Its a major set back as far as progress with the content goes but i think it will be worth it in the long run.
I have a working prototype and a buddy and I were jumping around the ocean together, a lot of fun.
Biggest challenges I have had have been with smoothing the movements and keeping everything synced up and in order.
I decided to just trust the client about the position of the player instead of relying on the server, this is not recommended for competitive games like shooters but if you want to write something to cheat with I'll be flattered anyone would care that much.
Ill also be making the save files human readable so anyone can change their experience, it will be up to the player.
I've also put this up on greenlight-concepts:
