Thank you! :) Weather is usually unpredictable, so I thought it would be nice to give the player a bit more control over it. The original idea was that you would get a weather forecast at the beginning and have to guess which timing would be best for the launch. After that, the clouds would slowly move to the left over time.
I didn't have much time to fully work out this idea and it could have been quite frustrating if you missed the timing and wasted the whole launch, so a little active control felt like the better solution for now. :D
