I also had issues with font, and don't know if it's on purpose or not, but each time a customer wanted made me an offer, I had to wait 2-3 seconds till the buttons to accept, decline or counteroffer were active. The time pressure was pretty hard, for my second play through I blindly accepted each offer, made it till almost the end of day 5 (had like 7300-7400/8000 goal). Still engaging and giving fun, if it had a bit more time to analyze the offers without time ticking, it would be even better (my personal opinion, might be wrong) :)

It took me a moment to understand everything, but it's a great concept that can be turned into a good polished game by improving the  UI a little. An issue I ran into is that you likely used emoji characters of something similar that cannot be displayed on all devices: 

Cool concept! I think the presentation could have used a little more clarity as far as what the different budgets meant and how the deal's inventory related to your stock. I also felt like when i haggled down a little lower that the customer should have gone up to meet me in the middle instead of also reducing their offer. I like the idea a lot!

I like your interpretation of the theme, I could have used a tutorial to understand the gameplay better. Also you had some unrecognized characters (like text characters) in the game that were not being displayed properly
