I'm addicted to this game. It's taking up hours of my life. I really hope this gets updates with more features and stuff because I'm absolutely loving it.
Things I'd like to see(but some of them are kinda big and crazy so I'm just imagining them, not expecting them):
1. Some kind of arrow that will point to where the passengers will slot in when you drop them. And maybe X out the cart when you hover over it and they won't fit.
2. Passengers with abilities that change the size or other characteristics of the ones they're next to. Obvious ones would be dieticians making adjacent passengers thinner and cooks making them fatter. Maybe other passengers could do other stuff, like stacking bonuses for the longer they're around, or adding likes/dislikes. Maybe even new passenger types somewhere down the line, too.
3. More info on the passenger bonuses and penalties. Some clearly give better bonuses than others, and I'd like to see that indicated with something like multiple pluses and minuses depending on the strength.
4. Upgrades! It'd be cool to turn the points into money and get to use the excess for something, like making the carts longer, or adding more carts, or specialized carts or seats that add buffs to a specific passenger type(or a group of types) or affect the passengers in some way(make them thinner/fatter, make them stay longer, increase points but reduce staying time, etc.). Stuff like this might even be for a seperate endless/management mode.
5. Bigger. That is all.
