Great that you liked it.
I consider adding some music and sounds effect but we will see when this will happen.
commenting again after I've played some more. I think the game should have secrets or some way to get characters to stage 11. Like if there was some hidden thing in one of the backgrounds to click and activate a dialogue or a battle (with a special ending). Orrrr, in Veronica's case, you could just add another stage that appears if you keep trading with her after stage 10. Lmk if you think that's a fun idea
