Quests I've been slowly working on improving. I was definitely treating them like 'hints' instead of directions at first and that's clearly incorrect. I believe I know why it reminds you of WaB, we both clearly started from the same set of RPGmaker starter maps, adjusted them for our own stuff but let the maps inform some early decisions. Also, for sure, I make try to hit a really good balance of content types and making them all not feel shoe-horned in.
Amy is Allen's offscreen sister. Her room is the one underneath Allen's, Allen refuses to enter unless you have the quest where your looking for something from her.
RPGmaker has an annoying issue where unless it "knows" theres a save in the location it dosn't attempt to load it. In the game, make a save in the file slot location of the new save file you want to import. then overwrite that save with the new one you want to import. when you reload the save you should be able to load that imported file. you might need to additionally restart the game after overwriting.
