Ok so there's a lot of good here! First I love the kinda stop motion vibe of the animation, it's both creepy and nostalgic! The whole train was really cool with a good atmosphere too.
My main gripe is that the game is very very dark, so the items are almost impossible to see. I also ended up lost in the generator section and eventually gave up after 20 minutes of wandering. ^^' As for the items, it took about an hour wandering around without understanding where I was supposed to go, until I found the passenger maniffest: maybe having the attendant tell us "please, there's a free seat on row (whatever)" would prompt the players to go check there, and putting the manifest either on the seat or making it lit up a little more so it's easier to spot.
As for the key the attendant gave me, I assumed it was added directly to my inventory and didn't check the floor, maybe a sound cue would help? Like if I heard the key hit the floor, I would pick it up.
Also making the flashlight brighter when it is on the floor would help, as walked past it at first?
Overall a fun experience, I will try to get back to it later to try and finish it.
It has a lot of potential so I hope it helps!
