You chose a very fun, funky, song for the background music. I would have loved some sound effects to go with the backing track; pouring sounds, alarm bell, maybe steam for the angry boss.
It would be nice, in a future iteration, if there was some visual relationship between the bottle size and the amount of water in the bucket. I felt like I was just guessing rather than visually estimating.
All in all, a cool idea. Great work!
