Very nice, the music and visual design really set the tone nicely, and while the mechanics are simple they're also engaging enough I got all the upgrades and hit $500. I found the pace overall relaxing to begin with, but I bought the bartender immediately so I'm not sure if that sped up my game or not.
Also it's nice to see Construct 2 getting some love <3
Overall nice work for a 7day jam!
If you're adding more mechanics going forward I'd suggest something interactive to do with the honest patrons? Maybe some sort of "rock paper scissors" action type choice for different types of patrons once you greet them? Learn the types of reply to get the most tips or risk loosing your tips with bad choices? Could also play into the up/down-votes thing you've got in.
