Hiya there,
I'm glad to hear you're enjoying Chapter One--that really means a lot to me~ Happy early birthday by the way--I hope you have a great day!
On the subject of Quest Failed merchandise, while I have thought about it to some degree, admittedly it might be quite expensive to get things as elaborate as plushies made. At least in bulk. Maybe as something super special/collectible down the line in limited quantities!
Though things such as keychains, buttons, etc. would be a lot easier to sell and distribute I think, if there was ever any interest in those!
