Love it! The art is great!
I get what JMC-87 is saying about the movement being sluggish but after a few rounds and figuring out the boost controls it's better. My only real criticisms are that I don't see a point in moving to the sidewalks to collect the roses if they're just a debuff, and that the birds fly up so fast that I can barely see them coming. Maybe a speed increase as time goes on?
Great job!! :)
