Wow have to commend you on coming up with something original. Sucking flowers into space is not a genre I see often. I can tell you put a lot of work into the graphical aspects of the game, the gradients and randomized flowers are very nice.
Thanks for your ideas; I feel the same on some of the things you mention.. Actually, this game started in reverse ( "I have a nice idea about making flowers, how do I make a game from this"?), and I also wanted it to be funny and to do some characterization (face expressions and so). The critters at one stage even pulled their tongues at you, but had to remove it due to size constraints
I found I introduced a bug recently in the game, and that's why probably you haven't died
: The seeds drop your health to zero, but don't kill you. Even with health=0, no matter how many seeds hit you, you're still alive... You have to crash into the ground with health = 0 to die. I'll change this so that when your health drops to zero, it's over.
