There's some stuff here I really like but it didn't make me want to keep playing much after failing.
The art is charming and I particularly like the backgrounds and some of the enemy designs. The way the character gestures left and right as they switch directions is really funny and genuinely made me smile.
The bubble mechanic didn't feel very intuitive, the room which "taught" it didn't seem to require me to use it, so I never really learnt what it was for. I like the "pollen" pickups as a concept and they felt nice to receive.
My biggest control complaint was firing upwards, which depending on which horizontal direction you'd previously moved in... this could be a neat control quirk to master in a larger more complex game but here it felt very frustrating compared to just letting the projectile go from the centre of the character upward.
Jumping felt a bit floaty and like it didn't have much character. I think later I probably needed the bubble mechanic to get past some environmental challenges but I just didn't know how to use it by then.
