Good.
This game is a great game for little children! Well done! But still, there are some annoying things that you should fix up for the sequel...
1) The end-tunnel bug. When playing a level where you can see the end of the end-tunnel, the flower just stops there and then disappears...
2) The MIDIness of the music. Try adding samples of real instruments for horns instead of using the MIDI wavetable. Please.
3) The main character is a smiley. C'mon man, use your imagination! It could be, like, a football, an orange, a bowling ball or something... (BTW, in the sequel you could make the player able to choose which character he/she wants to play. Go figure.)
4) The annoying sound. "Whee! Whee! Whee!" goes the speakers when you are surfing in a wind lift. Is it possible in flash to loop in the second 'e' to make a continuous sound during the flying?
5) Another feature I'm missing is aborting a level. When I pressed 'ESC' I thought the level would be exited, and I would go to the level map. In a game with level maps this is a must.
Overall, good game. Few flaws, fix 'em and make this go diamond! (Among children ;)
