Interesting game. It's something different. The graphics are good, also the movement feels good. At the beginning I was not sure how it works, but after some time I managed it. I don't know if I played it right, but mostly I was outside the sales table. Maybe put the shelves behind/below the salesman? Or change the layout a tiny bit. The Upgrades were good, they gave me a temporary aim.
Another suggestion: Remove the colliders from the customers or change it a bit. The first problem was that the collider was too large (y - scale), so I couldn't run past them if I was right behind them. The second problem:
But things like that are normal in a game jam :D
Everything else I didn't mention was fine and well executed (UI, Introduction, red Arrow which points at the shelves etc). Overall good job.
