Are you trying to complete the achievement for finding all the petals in Onirike? The developer posted the following map on the steam forum. I ended up with 62 petals left when I got the achievement, I think that means there are 1262 petals in the game. but I’m not sure about that because every 100 petals turn into a seed.
And it might help you, I missed the petals that were mostly right on the map, on the right of the magic doors thingy.
Thank you for using my guide. If you found the guide helpful, please consider following my curator page.
