Great job! Love the idea, the sounds, and the visuals! It was cool to fly around as a hummingbird! I see what you mean with being able to fly through the ground, but if I wasn't aware of what was going on, I naturally stayed away from the ground, so the average player might not have noticed. I will say that the collision of getting nectar from a flower was fickle. I saw it once, but then reoriented myself and never saw it again. I wasn't able to collect nectar from one flower :(
Still a fun and relaxing game and a cool start to something special, good job!
