I am glad you are enjoying the game.
About shipwreck, wanted something different than just a copy-paste city builder game and made some very clear design choices to make it unique. Shipwreck multiplayer is fully functional. The second you choose your colony name (when you start a new game or when you load your game) you are logged on the server.
Wanted shipwreck to have a seamless style multiplayer. You won't be sent back to main menu when you lose connection, no registration to play, etc.
Code, art style, and game design was done by all myself and have been making games over six years but never released any except shipwreck.
