Cool concept!
I think the small dialouges with the bat-companion add so much more depth to the experience, really nice.
I was kind of stuck for a while in the abandoned school level, because i iritated by the two massive light sources where you kind of disapear behind and because it took me a while to understand you are not supposed to find a way trough the wall that is in front and only half visible or really short in height.
maybe a bit unlucky level design but the rest i quite enjoyed.
Its a really cool game you created there!
PS: there is a glitching piece of wood in the beginning with no texture or a weird white material (?)
