ive just got into this game, it seems really fun, but i wanted to know if my time is low enough, can i just submit a picture, or is video required

Video is required for all submission. OBS is pretty easy to use and record your stream, and I actually suggest streaming to twitch as it saved your vods and from there you can make a highlight of the actual run that you want to submit since it takes less processing power to stream then it does to actually record locally.

It's worth noting that streaming to Twitch, even with that advantage, can be a bit difficult. My internet and living conditions both make it nearly impossible to livestream, so I have to record everything offline. If you're going to Stream, OBS Studio is a good option, but if you're ever considering becoming a full games Streamer I recommend Streamlabs, which is like a reskinned OBS that includes widgets like Donation trackers and on-screen Popups when people follow you. very nice.

Actually I just read the rules and it looks like they were never really built. I want to suggest then when someone gets the mod role that we update the rules just state that videos are required for submitting times and that we only use in game timer for it. Also, what is everyone's stance on the damage glitch? Me personally, I have not been able to recreate once in about 100 attempts but just cause I'm bad at doing a glitch doesn't mean I think we should change it.

I second what @CharlieCreston says. I forgot that internet is a thing for streaming for a moment (sorry). Streamlabs is way better then OBS, both for streaming and even just for recording. If you plan on doing more runs/uploads it's easier to use it to create overlays and such.

What are you asking specifically about the double damage glitch? I don't see too much of a necessity to split leaderboards over the glitch, since it's just about the only one found in the game. I feel like it adds a higher skill ceiling to the leaderboards as is
