The game is awesome and the idea is great.
What can be improved:
Cloud movement is a bit clunky
You can also make a Shader for the cloud
What I liked:
The idea is very unique
What I want to know:
How did you make the rain?

Hi! Thanks for sharing everything in such detail, I really appreciate it and glad that you liked the idea! Will definitely look forward in improving it after the jam.
As for how did I made the rain effect, it is just basically a bunch of tiny blue capsules spawning in random positions under the cloud. It's simple, but it works XD
