Interesting game, but the difficulty level is inconsistent. Some levels are very easy, some are difficult, but the challenge doesn't increase witht eh levels.
I like it a lot.
The game has a pretty steep learning curve, but that's alright, and it stays challenging allthroughout the game (those damn lava fountains at the end drove me crazy until I figured it out :D).
I like the game a lot, but it's just a touch too easy for my taste, especially since the level names often give a very strong tip on how to solve the level already.
There's no sense of achievement, at the very least it needs a scoring system or something. And please give it a more meaningful title - nobody cares if it is you first or 17th game.
A strategy that worked well for me to get the hard badge was not aiming at 45° but *horizontal* (or close to that at least) - that makes the fly so fast that he hits enough bees quickly to keep him afloat at first and it makes power-smashing him easier too because he doesn't drop as fast from "outer space".
