Anything missable?

[visighost 1,619]

I just started the game last night. Totally in love with the Moebius-like art and the music, only a little disappointed with the kind of jagged animation.

 

I have looked at the Steam and GamePretty guides, and while neither flag anything as missable... they don't mention that nothing is either. Can anyone in my favourite community confirm either way?

 

Thanks!

As far as I was able to tell during my playthrough, nothing should be missable.
