We used to have a category for it on the leaderboard but nobody ever submitted to it so I removed it.
I've been compiling my strats for this game for a long time in a playlist and wanted to increase visibility to it, especially to those who don't use Discord. There's lots of stuff there that can't be found anywhere else.
I added it to the guides section (https://www.speedrun.com/tmnt2/guide/a6utb)
I've tinkered with the idea of an IL leaderboard. It's just such a headache with all the different variations. There also hasn't been a whole lot of interest in it. There might be more if the timer wasn't skipped over at the end of each level in runs. If you're interested in IL runs I encourage you to do so even without an existing leaderboard.
Unfortunately it's going to have to be something that people deal with for the time being. The queue is still hard to keep up with as it is. Timing 15 instances of "waiting for players..." adds a ton of extra work. Then nearly every co-op run would have to be retimed, which is a massive amount of work.
I heard someone say the AI is more aggressive in Okay so you don't have to chase them as much, resulting in faster times. Unsure if that's true.
Or remote play directly through Steam.
You might be able to use a program like Parsec to work around that.
Is the waiting for players occurring during character select? We just decided to change the timing to start on character control, so if that might answer your question.
The only problem with IGT right now is it doesn't display total time at the end. It's still being considered as a possible option.
You can try taunting your way through the game if you want, it's not going to be fast
What about stopping the timer on the last hit? There's a clear visual indication of when the demon is officially dead: https://imgur.com/a/L7aMBiz
You still have control but imo that's a mostly meaningless leftover rule from SDA. Pretty sure once the last hit is registered there's no stopping the ending from playing, so the game is completed at that point anyway.
