The art is amazing and the consistency between UI, character art, and the train is very well done!
Unfortunately I found the story to be horrible.
A lot of useless information that doesn't add to ... anything really. It's not even lore.
The AI says he was called X before a colleague of his was called X (this makes little sense?) and then the main character calls the AI "EVA" completely ignoring what the AI said it was called.
Overall the text is sometimes cringy and pretty infantile, other times it doesn't make much sense what they are talking about.
What stopped me was that I didn't understand how to start the engine. I don't fancy hidden object puzzle games so I will stop playing very soon if there's something not explained that I need to find out by clicking a lot of possible interactable objects (because with pixel art it's a bit hard to understand what certain items are sometimes).
I hope you continue working on the game! Due to the art, it seems like it could be something amazing, albeit not a genre for me.
Good luck and put it on Steam one day!
(By the way, I would put the credits (art, and c3) in some credit page because it ruins a bit the cool look of the main menu, the icons are very saturated in comparison)
