thanks for playing!
regarding the seat colors, here's my response for another similar comment:
"the initial idea was that every train car would be unique in its own way, and that anomalies are spooky variations of any of these train cars. so then the game loop would require you to remember not just one train car in the train, but all of them.
in the end we didn't have time to make the train cars too unique (would require a LOT more art assets), so we settled with chair colors and handlebars as ways to differentiate the cars. but then i totally get how those could get misconstrued as anomalies. i think if we did make the cars different enough, this wouldn't be that much of an issue, but i could stand corrected."
regarding the levitating guy, you're not supposed to pass thru him - seeing him indicates that you missed an anomaly on the previous train car
