Amazing audiovisuals—the pixel art of the train interior looks incredible! Overall, it was a really fun experience.
By the way, I found a little exploit that I didn’t use because I didn’t want to ruin the experience, but just in case you didn’t know: if you zoom in and out of the browser quickly while standing against the wall just before switching trains, you can briefly see whether the next room is red or normal.
I know it’s a pretty niche bug, but hey… that’s just how I play, haha. Great job! :)
