Thank you so much for checking it out and for the feedback, we really appreciate it <3
If you started seeing only Bertha selling a Vase forever right after her selling the Dinnerware, then that's because the game ran out of different encounters (we were planning to make at least 4 more, and had already drawn the rest of the characters, but we didn't have time to make the objects and dialogues). We didn't have time to make a screen explaining it or anything, but we'll have that into account when expanding the game!
Regarding the music, we were quite sad not to have the battle song ready for the game before the deadline, so I totally get it :(.
About everything else, thank you for your words! Probably part of the reason we couldn't do that much content was precisely having to implement a game engine from scratch in jam time... (scene transitions, cutscene staging and so on). It's a terrible way to make a game in a short timespan but an awesome way to learn about game development and about designing complex systems! I can also say that my boyfriend (who mainly focused on making all the artwork) is really happy to see that you found it cute!
We still have to play your game (as we have already a quite long list of games we want to check out properly as they deserve <3), but we'll check it out :D.
