It's interesting, quite the unique concept! I love the whole physics aspect of it where your characters fly out of the cars and you can catch them: everything about it felt very intuitive, like how if you don't go fast enough on a loop they'll fall out at the top, and so on, so great work on the simulation with that. However, it was kinda short-lived with only one level to go through, and maybe it's just me being stupid, but I was super confused initially. I thought at first that the whole challenge was ensuring as many customers stay alive as possible at the end, which you can do by driving safely or by catching them, but instead it was rating you on distance, which didn't seem logical to me since it always ran out: basically, the whole aspect of catching customers giving you fuel back wasn't immediately apparent in gameplay or logical to me. Perhaps it would help if there was a little blurb at the beginning to describe the rules/objective to let you know that people flying out of their seats is a good thing (because it usually isn't haha), or if, when you catch a person, you'd see their 'excitement' as a particle that flies over to the fuel gauge and fills it up. Also there were some slight annoyances like sometimes if you just have a slight bump, they'll fly up a bit and then fall straight through the cart, possibly due to some fighting over their seat priorities, not sure. Anyway, very interesting game!
