1) Love the feed, realized its nice to see other random games i have no connection to. Wouldn't have thought it would be entertaining but its great.
2) Export video to camera roll: im sure some folks will want to export the whole thing (update: now i see that you can do it when you full screen it, may want to move that to the menu on the video processing screen).
3) Creating sharable clips that are branded can definitely help grow the app. Seems like you may be able to identify types of highlights, so mashing them up, with some graphic overlays and voiceovers (think play by play with elevenlabs). Have a few folks who work in this space for sports teams that may be able to give some guidance.
4) Turning the screen off while recording is a brilliant feature and is reassuring
5) Realtime scoring is likely harder but would be a killer feature.
Love this, all the best on the development!
