Thank you so much for the detailed review!
I'd say we spent 90-95% of our time creating the simulation. This led to some of our game mechanics not being explained well (or at all).
Auto purchasing was initially a dirty fix for not having a UI to buy things from, and one of our devs got super used to it, so we added it to the purchasing menu. I'm personally still unsure if having it on by default is a good idea, but can't deny that it's a good QOL feature.
Also, THANK YOU on the rollercoaster idea. Our Artist, Nathan, gave us the sprites on Day 2 (for me anyway), and those types of situations came to my mind immediately. Glad I'm not the only one who thought about it, and it's something I'd love to work on in the future!
We're also working on a post jam update! A lot of these little things got fixed, added some explanations to game mechanics and generally polished the game further!
