I haven't tried myself as composer yet, but could think of edits for images (e.g. as youtube thumbnail, media's trailer intro as image, etc.) or especially if looking for writers who dub/subtitle by texts ...but I can't ASL (sign language) or translations by voice. Still can inspire by level-suggestions, creative nicks for worlds or objects to interact with, up to "alternate endings" where not only one way rather multiples can be explored, affected by gameplay's path to choose from & guided to sections that don't seem to be unlocked at least, in the first glance yet.
