Feel free to show your PB runs you lost from any point
Runs lost: 24:XX (13) (Most due to lag, one due to softlock) 23:XX (5) (Lost one due to softlock, 2 to errors in water, and 2 to lag) 22:XX (4) (Lost 3 to lag and one to being dumb) 21:XX (1) (Lost due to lag) (30 FPS btw switching to higher refresh soon)
I would say that the limit is a low 15:XX or a high 14:XX, since your runs are missing some movement fixes to save time
The problem with doing this is that you can very easily clip through the elevator platform, and can soft lock the game assuming the next checkpoint isn't loaded properly (lost a 23:XX pace not 30 minutes ago to this) It would probably save 0.5-4 seconds per stage going upwards (depends on mash speed) but it probably won't be needed for some time
Big Tower Tiny Square 2 is now an official speed game https://www.speedrun.com/btts2/ To any moderators who might be reading this, could it be added to the Big Tower Tiny Square series (If anyone with experience is maybe willing to moderate the game pm me)
