would screen flicker/image static be able to count as a kinda "particle" under this rule:
[you may] use custom particle effects, so long as there is only one type of particle being used (e.g, cherry blossom petals, fire, etc.)
or would doing that break this rule:
[you may not] use masks (via multiple separate files) to create secondary versions of the background image on screen
(essentially my idea is for the game to be like communicating with someone in outer space through video, so itd be nice if i could add particles of static/flcikering to the "video feed". the amount of static/screen flicker wouldnt change through the game, it would be fully consistent - i would merely want to use it as an ambient particle effect to make it feel more like real video communication. but im just not fully sure if this would be too much of a "mask/overlay" to be allowed?)
this is the closest example i could find (from RE7) - notice the lines making it look like a video feed? id do something similar, with a bit of looping particle flickers
