Hey, im really late to replying, but thanks for the feedback!
For the part you got stuck in, that's definitely an unbalanced-unfair part that I hope to fix in a V2 update, sorry about that!
You pretty much gotta max out your jump height and jump on top of the icicle on the wall, then hop onto the blinking block for a moment before hopping to the next platform quickly if I recall correctly
The movement definitely is quite frantic, that's something I know I should tone down in the next game I make, as for the walljumping/burst, I think calling them bad is a bit overdramatic, but they're definitely not great either and feel unsatisfying
The game has a clear issue of communication, I think all these comments have thankfully made that aware to me. For an update, i hope to be able to communicate the statue gimmick and the controls/mechanics better.
I agree with pretty much everything you said about my level design (though checkpoints are less frequent on purpose as to invoke some level of endurance), the safe environments when introducing a new mechanic was something i should've added, and the lack of them can really be felt when the ability to jump is revoked.
The level design was somewhat rushed (and some other parts of this game too) and I probably should've fine-tuned it a bit.
But yeah, thanks so much for the feedback, i really appreciate it!
