This is a great game! Lots of polish, a well thought out gameplay loop, and great visuals and audio. You’ve received lots of feedback on the controls, so instead I’d like to mention that I think this would really shine with some adaptive music.
Like, introducing a fast paced drum beat when you pick up a chilli, having some kind of happy travel motif when you have passengers, or having the music turn big and ponderous when you have a certain number of carriages.
That’s just a suggestion, of course. Overall this was such a cool game it doesn’t really need it.
Well done!
