I loved the effects and post precessing, very beautiful!
But this game has just 2 minigames, unfutunetly...
Also the pong game is very laggy for some reason.
I's like to know what shaders you use in this effects, I liked it so much
I use urp post processing effects it is packaged with unity
if you are talking about the lines effect like vcr on windows version i used a vcr effect there's a tutorial on YouTube
