Ok here's a mod for Ultra in CtB mode. Lots of unrankable issues that I would suggest you fix
00:10:652 (3,1) - Impossible edge dash, increase distance to make a hyper or reduce for playability
00:13:652 (6,1,2) - Hyperdash into edge dash is unrankable, reduce spacing from slider head to tail on 1 + either increase or decrease distance to 2
00:17:126 (1,2) - Increase the distance between these two for better playability, since previous part is all dashes
00:36:705 (1) - slider tail is too close to previous object because plate has too much momentum, increase spacing
00:42:705 (5,1) - large edge dash, increase spacing for hyper
00:44:916 (1) - only caught a little bit of cancer from trying to follow these droplets. Could increase to slider tick 2 to fix.
01:07:652 (1,2) - Here patterns start becoming unplayable/impossible to fc. Using two 1/4 sliders in a row on each one creates impossible dashes that constantly kill flow. Using more patterns like this would significantly increase flow and up the diff.
01:13:968 (1) - All of these jumps are at the farthest possible distance from each other without being hyperdashes, which makes it really unplayable and underweighted.
01:16:021 (4,1) - nice pp, just increase spacing here a little bit so this is also a hyperdash
01:16:652 (4,5,1) - If these were unstacked it would really improve flow when ending the dashes
01:24:389 (3,1) - These edge dashes are near impossible to play
01:29:758 (1,2) - Over the top edge dash, increase a little
01:50:284 (3,1,2) - Pixel dash, also known as the most unplayable pattern in the game. Increase spacing to 2
hope this helps with making it more playable for ctb, since right now it's unplayable in that mode <3
