Cute game!
Definitely on the easy side, except for level 25 which is a difficulty spike and a half.
Levels like 24 where you're just collecting flowers in an open area are kinda boring, the rest are okay.
You can bounce off spiky vines if you collide with them while invulnerable, which doesn't seem intended but doesn't break the game or anything.
It's not the most exciting game design-wise, but the visuals, effect, music and UI are all good, if this is meant to be a "tutorial" game you knocked it out of the park.
