This is a great witty premise. I like a lot of things here--the writing feels sharp and fun, the wacky pizza ingredients, and the van's animation is very quirky. I liked the balance of map movement to pizza making. Plus you've just created a big scope of game for a weekend jam.
Two suggestions. First, I'd like to have some hints about what's going to happen at the next node, Slay the Spire-style--for instance, maybe you can only set up shop at certain nodes and so nodes are either shop locations or random events.
Second, I could have done without the physics during the pizza minigame--it was hard to judge how to drop the ingredients in the right place, and I wasn't sure how squarely on the pizza it had to be to count. If you want to keep the physics I'd like it to be real clear where you're dropping things. I'd also like a visible timer so I know how long I have.
Overall, nice work though!
