Ah, RPG Maker, how I missed you.
Now, I don't know how seriously you want to take this, but I think it needs more funny moments other than cutscenes. Like interacting with the environment should provide some funsies, and also with items and other micro-quests, like bringing a piece of beef to the grandma and she yearning to stew it but not being programmed to, etc.
"Vanilla" RPG Maker games are a dime a dozen, even back then, so you have to put in much more work to make it stand out.
