Very nice!
I decided to try it without dash grace jumps and managed to lower it to 2, 1 in 1300, 1 in 1700, and 1 in 2600...
In 1100 it's possible to do a spike jump on that leftmost side and then continue as normal
In 1800, it's very tight, but you can just barely reach that first balloon by getting to it at it's lowest pixel
And in 2300 you are able to do the same trick as before
Also it might be possible to get one off of 2600, but I'm not sure, I keep dying at the brown X in the image
EDIT: Wait... you could do the gemskip strategy to beat it... give me a bit to do that
EDIT 2: did it
It's kinda hilarious to me that I missed those simpler solutions and chose much more annoying solutions like in 2400 and 1900 lol, thanks for those
