How do you know you found all flowers?

Hi, I am on the first level and I am pretty sure I found all flowers but I am stuck in this level. I am not getting to any other levels. Nothing is happening other then me just going around this level.

If I missed one, its pretty hard to find it.

No you are not required to collect all of the flowers, at least not in the first few levels, later on you have more strict goals in order to progress, so you are probably not moving in the right direction, kinda let the wind take you where it wants. Try getting some camera altitude for clues.

if you are talking about the secret flowers there is 3 in each level.
after finish a level if you got any secret flowers you'll get a petal dropping for each flower you pick in the correspondent flower vase in the menu.

after that when you try to replay a level there should be the 3 petals in each vase

there's a good guide around here with screenshots
