Thank you so much! I'm glad you enjoyed our game :D
We actually really cheaped out on the CRT effect. Instead of doing the responsible thing and using a shader, it's just an semi-opaque overlay graphic (alternating black and transparent lines) on a separate Camera Space canvas, so it gets affected by the post-processing.
The screen curve is using the lens distortion post-processing effect from URP.
Thanks again for playing! <3
