Pretty good
I thought it was somewhat good, provided a challenge. You haters out there, I agree it gets kinda boring. The thing about it being too hard is bullshit guys, if you actually think a little then you can figure out soon enough and besides if it is too easy then it would be beyond boring.
something that could definitely make this much better is by adding in new challenges each level (different types of clouds, wind, etc) instead of just storm clouds and rain clouds.
