Indigo Transept and breathing underwater

[Xmax4k]

I feel like the game expects me to have more than 1 tile of breating by this point, but i didnt get anything like that. Im down to the final floor of Aspe and regular enemies kick my ass (also foe from past floor became regular enemies - giants).
5th floor of Aspe (the one with wardrobe behind illusion door) has 5 green exclaimation points, but i dunno how to get there

I was stuck here as well and so were some others. I'll give you a hint. You Shining Light ability shows you where you can jump while active on all floors while looking at the map.

Full answer if you don't care There's a jump you can do on the gallery floor that will help you progress

I also got stuck here for a while, and for what it's worth, you'll get the High Jump ability before you can breathe underwater. If you've gotten that, make sure you also check the transepts for areas where you can use that, and as mentioned, Shining Light will mark conspicuous squares on your map, so you can use that ability and then just look through every level of the map to see what's been marked.

That hint was enough. Holy crap, was that easy to miss.
Thank you :)
