After exploring everything outside except bathhouse i'm still missing something or should i just spend 5 coins and go to bathhouse? Also thank you for the help
You still can find some coins at the beach and inside dinner near of door. At Kaise's farm you can find a lot of money. Is not a spoiler, version 0.7.0 will very different in a lot of ways. Because in 0.6.0 gameplay is linear, you can do what you want, plot will not let you do something wrong. If you sure you find and see anything then just continue plot.
