Multiplayer is planned :D Once the game is on Steam it will use the Steam API for multiplayer, so you can host a game and have friends join. Will also probably support joining direct via IP if you wanted to host a server without steam. Thanks for playing!
Alright. Also, wow 14 months is really good, I started work on my own voxel survival game about... 3, months ago, and I'm still stuck on the world gen parts! \:
