Seeing your post on discord, I remembered I forgot to let some feedback on my experience.
The stain DEPUP and PUP that take the full screen is a terrible idea, they happen a lot, they're invasive, they cover the rest of the game.
Also there is a lot of pellets that drop and catching the one you need is very hard and sometimes impossible when two of them overlap and break your combo.
I like the idea of shadowbox for shadow !
