I'm not a mod but I do not think a screenshot would cut it as the rules do dictate video is required as screenshots can be edited easier than a video. Also its a World Record on 3/5 categories (which due to the time I presume it is) It could be seen as extremely unfair.
You could try and get the game added to speedrun.com (also congrats).
I recently decided to do a 12 Labours of Hercules II: The Cretan Bull Level 1.1- Unblock The Road Expert Speedrun because I thought why not however the Moderator for the game has not been on in 10 months meaning he is unlikely to see my record breaking Speedrun. What should I do? Do I do anything?
Because some people prefer to use something different to youtube.
When Yeventry made his post on doing an IRL solitaire category it got me thinking on other possible runs then I thought of a Low% category were you have to make the fewest moves possible. I realise that this would be a laborious run to verify as you would have to count the moves to make sure they were not cheating however I just wanted to put it on the table.
Every game that has been mentioned has an IRL as a misc, however for some reason the misc for pencil sharpening simulator is only 2P and not the 1P version and 1P is its own extension.
