Wow, thank you much for the praise and honest feedback, it means a lot to us!
Attention to detail / having unique customers like the grandma etc. was very important to us, I'm glad you liked them as well!
We actually also had the idea about small change resource management, but it got scrapped (mostly due to time constraints). Some version of this now exists as "there is one type of coin missing on day 4 / 5".
I've never bothered to make browser-playable versions of my games, but you might have a point. Maybe I'll start making browser versions in the future.
There will be an update at some point after the jam fixing a few bugs and potentially adding an endless mode, we'll see if we have other idea we want to put in there (and find the time to do so).
Very happy you enjoyed it!
