Thanks for the feedback!
First off, you're right—it really doesn't feel super responsive. Honestly, I'm not even sure if it's because of the animations or something going on under the hood. For things like the storage, you can't tap it unless at least one item is dispensed, which definitely hurts the UX.
Second, I could've sworn there was audio feedback, but yeah, it's completely silent in the uploaded build. That feels like a bug to me.
Third, totally agree with you—preventing them from overlapping should be an easy fix. I really appreciate you catching such subtle details! I'll definitely get that sorted out.
And thanks for the ideas! An endless mode sounds super fun—I honestly didn't think of that! I originally framed it with a clear ending in mind, but having a wide variety of customers pop up sounds like a blast!
