Thank you! The best way to earn credits should be crafting from raw resources, but for now, logs should be enough. I'm glad you're intrigued, there isn’t much content yet, but I'm working on it after receiving encouraging feedback. So yeah, for now after opening solar farm there is nothing much to do.
Clothes are also in progress, although they will come later, because I want to create a customization system for the player, and it takes time to draw the animations.
