Thank you for playing! You are right - especially the sound design is one thing I did not manage to get done. I also wanted to animate the Scaler and add more customers to it.
As for the depth of the scaling, it is very shallow and could use some more mechanics. For example, I was planning to include the ability to obtain some empty containers (e.g. potion flasks), so you could weigh them against their full counterparts to weigh their contents accurately.
Which ending did you get, if you finished the game? :)
