Looking for a name of 2D Horror Game

Im looking for the name of a 2d "horror" game i played like 4-5 years ago..

Its a basic Jump n run game. In it you play a flower thing (?) and at first the levels are happy, colorful and peacefully.
But later they turn dark and scary and black hands come out of the ground to kill you, also the enemies turn from happy into scary.
even the flower you control gets a scary face now..

Oh and it was a free game..
thats all I remember :(

Sounds weird but i definitely played this :D

Can anybody help me out?
