If you clicked on the TV that was hanging at the right side of the store, you would've been greeted with some casual Kevin Mcleod music. The spawn rates are randomized based on your rating with only a 10% chance to spawn every second in the first level. You might have gotten unlucky whoops.
As for selling fish towards the front, I will definitely look into trying to make it feel better.
Thanks for all the feedback! 🐟
