This has got to be the most annoying music I've ever heard in a game and I've played plants vs zombies nes port.
Also this really could use some feedback, even if simply the background of the bubble changes when you pick something up this would already help a ton.
I do really like that you didn'r just scatter things randomly but put frozen shit in the freezer and the bread somewhere else and that's all really good and makes the store feel alive.
This is a very fun little game but it could be improved. Maybe a bigger store, more items and definitely more feedback.
