Introduction

Taken from the comment of the user Darkness.
I just created a guide from it for quick access to it.

Also, if you need tips on how to find them without an exact location, then here is a good guide on this:

These are valid for 1-500 and above. For 501-1000, just add "500" and you'll know the stage, and so on.

Anyway, a hint on 101-110: you'll see a red and blue butterfly above a pillar each, in which teh game would require you to make some insane precise timing platforming to get there, but it's not needed: just wait for the butterflies to land on the pilar, then double jump + air dash towards the pilar to get them.

The one i was missing on 314 is just above a tree, not very tall.

Hint for 420: go from left above until 419, go through a hole in the building wall. Climb easily on 416

473 requires you to go from above right, 490 is behind the boss above, 492 requires you to go above from left.
