you know I would agree that at least Extreme is unbalanced, there's a jump close to one in high C3, but if this is impossible than I don't know what to tell you
just, jump on the thing and try different timings for when you start to move against the rotation
ok the SJ has tight timing, but it is NOWHERE NEAR "frame perrfect", are you holding the W key down for a full second??? Nil would be like Dimensional+ parkour intensity or something (LC6), yeah this isn't an easy trick but it doesn't practically require checkpoints for a human being to do it
about the balance, yes I don't know if X stage is objectively easier than X+1 stage (unlike the difficulties, the individual stages are not strictly increasing), the stages in the difficulty are the things I thought were harder than the stages in the previous difficulty, some people will find a thing way harder than I find it, I've played these Algodoo obbies since over a year and can beat class 5 stages with couple dozen attempts, yet if I played EToH I probably couldn't beat even a hard difficulty tower before I went nuts
