I have this phobia myself but have a curious fascination with it.

I started my game by making a spider spritesheet - not particularly scary, it was the upside down silhouette designed to look like the shadow of a spider on the ceiling chasing the player.

EVERYTIME I playtest my game, the animation of MY OWN giant spider suddenly coming onto the screen JUMPSCARES the life out of me every single time nearly (it turns up randomly). This is my own creation. I cannot bring myself to even try anyone else's game sadly due to this phobia... I just don't think my nerve can take it.

Sorry in advance, yes I am a wimp LOL but I think I'm tapping out of making my own game for the jam and too scared to play others. But good luck everyone :) I may come back to the next jams if it thematically tied to phobias because I think it's a great idea. But just my luck my own phobia came up first LOL.
