chapter 1 from batim and poppy playtime are quite similar
1 : starts by collecting items (batim)
poppy playtime Starts collecting items?
2 : Batim ends chapter 1 with a chase but cant die
poppy playtime also has this but you can die
3: has secrets( both )
4:tries to find the exit and escape ( batim im sure but not sure with poppy time)
So in conclusion they are kinda the same but poppy playtime kinda changes it
