Hey, thank you for checking it out and yeah there was a quite a few points where it was a bit rushed. I had initially planned for like a steal skill to get gold from enemies and to have a plugin to adjust the escape rates for the enemies but I just ended up using RPG Maker's default one instead. Ideally, with the gold obtained from fighting the enemies, you could have enough to buy from the shops.
Also yeah the Kasey ending should not have occurred prematurely. I actually had like half the game left after you entered the house lol, but I had to cut it out because of time. But I am glad that the auto save feature came in handy.
And thank you for mentioning the issue about not knowing how to progress in the overworld. I thought having the event triggers at the entrance of the castle would have been clear, but I should have expanded the detection area to perhaps the entire castle so that the player can more easily reach the target.
