And it's the return of the three hearts run as thisishowmymindworks showed that this route is faster by a few seconds (https://docs.google.com/spreadsheets/d/1isIGkvfF5sar-l7Ta2G8FXx4YeOqI0MuF7Y5VXZrTsQ/edit). And i didn't even do the three heart strat for grigori that saves another second.
My only significant mistakes were: -A failed boost jump before LMOOB (~1s lost) -Weak final fight with grigori because of my hand stupidly shaking (~2s lost) -3rd try GBJ in "Not so hard" (~2s lost)
Otherwise, there are still some faster strats in various rooms that i'm not doing: -GBJ in "blocked way" and "upward sector". -Chained boost jumps in "The Drain". -Warp Glitch in "Lost Mountaintop", "Before the city" and "Antenna Relay".
In the end i'm still very happy about the run but it's definitely possible to save another 5~10 seconds. It will just require a lot more work than just run grinding.
(P.S. I turned off autosave at the beginning otherwise my game freeze for ~8 frames each time i run into a checkpoint which blocks my input and screws with my timing. Also, i waited a bit before the final boss because my hand was shaking so much i couldn't even hold my controller correctly. This brought back many bad memories of osu! contests.)
