HI! Thank you for playing my game! I kinda forgot how the games work by now, but did you keep increasing your woods and crewmate? The ship progression should increase that way, but it's probably a bug if that does not work. I'm not developing this game anymore since this game is like my first try getting used to Unity and all assets came from other people, but I am planning to make a new fangame in the future, but it will be an R18 game, If you are interested, you can check my Patreon page to see how the progress with this new fangame project!
