Battle with the flower Bleah.
Mediocre at best. The two attacks are too similar, you need to make one more powerful than the other, but also make it harder to pull off. Plus, the enemy has no animation when it's hit, so half the time you can't tell if you're even damaging them. Also, when they die, it just goes straight to the next screen with no death animation. Lastly, there's only one thing to do - fight a few battles with the flower dude. You could at least give us more characters, perhaps ones that are unlocked by beating Arcade Mode.
