Thanks for the feedback!
1. Definitely gonna redraw all the food, they are a bit rough at this stage.
2. Your thought about the spam clicking strategy is helpful. This strategy is originally designed to actively refresh items because sometimes there will be item missing on the shelves. Even though this strategy might not be easy to conduct on later days, but players can cheat on earlier days with this strategy. If I have time to work on a post-jam version, I will reduce the random elements and make each day unique. That means different goals, different customers, different environment, even different mechanics for each day. Thus, I will re-design this spam clicking mechanic. Probably adding limitations to it or even totally get rid of it.
Thanks again!
