I'm already on my second playthrough lol.
I think I can get everything other than "Less than 100 saves" and "Less than 12 hours" on this one. I'll have to leave those for next time, because the others I can do if experimenting in a large amount of time with more than 100 deaths.
There's no way I can get 1000 light seeds, do 4 runs, find every combo, make a 14 hit combo, find two views and get to the lowest point in the world in less than 12 hours with less than 100 deaths.
