This chapter was a lot longer! I'm impressed with how quickly it came out despite that, good job!
Sorry that this is what I usually do, but I'm enjoying the game, so I feel like I need to point out some errors. This is something that happens with a lot of the NPCs in the main area: You can still talk to Kosaka from a few chapters ago in this spot; however I believe removing the event will make new players who are playing from the start unable to progress, so enabling a switch that makes this event no longer have a graphic after a certain point would help.
One last thing, it seems that your party members don't get recovered PV/PM so if they previously died or lost PV during a battle they don't come back at full health. And I really think that the game should either only have enemies on the overworld or random encounters (which the rate of need to be severely lowered) instead of both.
