Thank you for the feedback! There is no sound, there was just no time. It's our fault really for choosing a game jam in Christmas eve, but we did our best. There were so much stuff we wanted to improve, sound being one of the main ones that we had to cut as we neared the deadline (Imagine wanting to do sound design a couple hours before heading to a Christmas dinner). If we decide to continue development we will definitely give more love to those aspects, the shop being one I want to rework from the ground up. Really, I'd rewrite the game from scratch, but we have to see if we'd not rather move on to a different project.
Anyway, I'm glad you enjoyed it!
