(First, sorry if I make a grammatical mistake. English isn't my mother tongue) After see yesterday the post made by Shijifusu, I started to do this simple guide showing the order of the items in Misao: Definitive Edition. In my opinion, that's the first thing we'll need to make a speedrun guide. I'm open to conversations about this future guide!
Hey, so I've been super busy for the past copy of weekends and haven't had the time to lab anything super intensively yet. I have done a couple more casual playthroughs just to try and get a bit more fluid with the map (mainly for side rooms such as class 1 vs art room.) At the moment I always find myself heading to the rooftop first, just so that as soon as I get the seeds, I can plant them after the moment with Library. I know this isn't super helpful, but it's my thoughts on a run at the moment. Hope this helped a tiny bit at least...
As for the next step, I'd say it would be as Eddventure said, just screwing around in game trying to figure out a "optimal" route
I want to do a text with ALL the routes necessary to clear the game, as well as the necessary rooms to visit; our job will be to decide the most effective way to accomplish all this by finding an optimized route. As soon as I do this, I'll send you here or I'll create a new topic to talk exclusively about these routes (and I talk here if I post in a new topic). Good luck man!
