For Go Keepers (and any other game where it applies), can you either slow down the speed at which narrative text comes across the screen, or preferably make it click-through via remote rather than on a fixed timer? Or point out where the option is if it's there? That's basic accessibility. I can't read and explain to my 4 year old if it's hurtling through the story bits, and not everyone's a fast reader even without toddler accompaniment.
I need to be able to provide them context about what they're hearing, there may be words they aren't familiar with, etc. If the narrative just goes by, I don't get that chance, and they miss some of the fun/purpose of the game. You've clearly gone to the trouble of providing a degree of narrative structure, which I as a gamer appreciate. Just slow it down/make it available and accessible. They're at an age where they're starting to engage more with narrative rather than, as Terry Pratchett put it, "things just happen, what the hell."
