pretty good, could be a lot better
the basic gameplay you got is pretty cool. something i might recommend is changing the music, nothing wrong with the kirby music but it does get grating after a while. maybe have the music change as the map fills up, getting more tense, darker, etc. another thing is that this seems like a game design that will eventually become literally impossible, as the flowers will spawn immediately. or maybe you do have it reach a cap and i just suck :P
