Thank you very much! I been learning Blender and Unity as a hobby, I still don´t know how to animate but I do my best to work on the aesthetic and make it part of the overall feel of the game.
Initally I had only 5 levels, but then decided to keep it up to 10 (7-8 did not felt right). The fake clouds were the original idea, but the timer came along, as you said, to add necessary pressure and keep you on your toes.
