Good job!
I like the style, and the interesting idea about buying your supplies for an art simulation!
A few notes-
- I didn't have a frame of reference for how much things should cost, so I only ever went to one market and just bought random supplies.
- Hitting things with a hammer felt weird, I think it was the combination left-click-drag and right-click-click.
- Waiting for a customer to walk into position took a bit too long, in my humble opinion.
Overall, great job! I loved your drawings for those customers, haha!
