Good game. The design of the flower and the bees and spiders is nice. Really love the sound effect when powerup is used. That's a really cool sound effect.
I had some issues, though. I found the hitboxes to be a bit clunky. Sometimes I would get hit even when the bee seemed not to be touching me. Also, sometimes the enemies spawned almost along the whole width so there was nowhere to go to avoid them. So you should work on enemy placement and spawning. The background could have been better. The clouds seem too big.
Well done.
For a game technically about reproduction and plant sex, your game doesn't look unsuitable for kids. Haha. Oh, and your life powerup looks like a dragon ball.
