It's a good game with a cute pixel style and nice and cool physics (I like and respect that). I try to write helpful reviews, so I'll write about the minor things I noticed.
The game doesn't fit completely on my screen, so I didn't immediately notice the preview of the next flower, and my color information is cut off.
Also, while playing, I realized that I didn't understand when I was losing. Here, I seem to have burst half of the flowers in one move, but I lost because they somehow turned out badly (this also happens in other games of this type, where items can only be thrown from above, but it's easier for the player to track the physics and understand what's happening: for example, I merged two items to create a larger one, which raised an already tall row). Here, the player always loses because of the push effect, not because the field is full. It may feel unfair.
The flowers fly right to the edge from the very first throw, so I only realize that I've lost because they take control away from me, not because I see something go over the edge.
In any case, I liked the game. The physics and effects are awesome, as is the idea itself. Good luck!
