I really liked the concept of this game, it had a unique element to it, but unfortunately I couldn't get over the time it takes to pick up the flower.
It slowed the entire game down to a halt - I understand keeping animations in, but having it creates this weird pause in the gameplay that becomes slightly frustrating.
This could be avoided by giving you a flower on re-spawn, or causing a check point on picking up a flower to avoid having to the animation again.
Personal preference as well, but I think if the petal shot upwards and forwards, with you having to jump into rather than onto it would produce slightly better feedback. I found sometimes I would over shoot the landing, turn back on myself and petal-float backwards
Outside of this I think this is a solid puzzle platformer with an interesting and somewhat creepy yume nikki styile vibe to it.
