I think is my favorite game out of all the games from this jam I've played so far. There are a lot of elements to this game and you've executed them all quite well and integrated them superbly. And on top of all that, it looks great too! I can hardly believe you made this i this short a time frame all by yourself; seriously impressive!
Now for some nitpicks:
- In peggle, the ball will go exactly where you click. I think that would be nice for this game too.
- When the day is over, the sound design made me feel like I did something wrong, especially after the first run where I died before the first day was over. The sound felt pretty similar. (Were they the same, I don't know). I think it would be fitting to make reaching the end of the day feel like an accomplishment. Maybe a nice cash register bell could make the player feel good about themselves.
- That's all really.
I got to about 650 dollars on my second run, might give it another go later :)
edit: I think the one problem I can think of with the game design is that a lot of the upgrades increase the amount of things the player needs to juggle. It would be nice to include some upgrades which help out the player. Like lowering the chance of fires, auto shooters which have a small chance of shooting a ball after it's been available for a few seconds and auto sellers which add a small chance of fulfilling an order right when it's about to expire. I don't think my concrete ideas are that great, but it's something to think about.
