The tutorial is glitchy: can you give me the reason or a way to reproduce it? I'll try to fix it.
Too little animals? You wanna have more animals? Or bigger ones?
For the job menu, look at the arrows, you need to be fisherman before being diver. Also, above each column, there is the level required for choosing a job in this column. You can see in your inventory, above the level number, the job you chose. If it's not written "diver", it's because you didn't succeed to have it
Thanks for the feedback :)
