You have to unlock new teleport locations by interacting with them; if I recall the fighting tutorial takes places in the backyard? To get to the forest go out your front door and interact with the green light, head right until the next green light, then head left until the green light. Probably best though to go LEFT after exiting your front door to explore the 'outside-of-town' maps.
Would you mind explaining? I've never done a deep dive on the FOBS developer, though I recall hearing he hated people pirating his stuff, so I don't know if he has other stuff (I'd always assumed no). This game seems super similar in both tech, fetishes, and graphics and I've seen a couple of people saying it's the same artist but I didn't trawl through the whole thread and the DL page lists this as the only game by this circle (though the illustrator is on games by other circles).
