Could be all island jump puzzles or broken up into different leaderboards. Would be a nice 'for fun' category.
No everything people can and will do will be worth while on a competitive leaderboard to be tracked because they are usually very niche, and hold very little interest compared to more traditional runs. You can and should speedrun a game however you want but when it comes to havign things on a leaderboard it usually will come down to is this what people will be generally interested in for a competitive run. Should in some point more then a couple people be doing runs like this as an example, there may be a good possibility to revisit the request with the community and those that are current maintaining the boards to ask about the inclusion.
I agree with Seamus, I think they will be some people on those category, maybe to put in Misc.
I've already run Beach%, which aims to complete all Gestral Beaches starting from a new game. We could also do some ILs.. I would love a place on the board for category extensions but if not we can always keep a spreadsheet if we wanna track the fun categories. No reason we need to be confined to this leaderboard!
Personally, I plan to do an “All beach”.
It would be on a save with the flight unlocked
I plan to start by entering the first beach and time to the resolution of the 5th.
Let's see if other people are interested :)
