neat idea but it's way too cryptic.
my playthrough was this: i spent 12 minutes doing random movement until the door opened for a reason i was unable to figure out until i had the revelation that the symbols were not the "untranslated" version of the text you see on each note, and instead probably meant something else; i noticed that the weird black shape on the note that says "CRESCENT = SLIDE" looked a lot like the sprite of the player sliding. then took a few mins of experiments/tests and analyzing the symbols to figure out what TRIANGLE might mean, and a bit of how these symbols map to actions chronologically. i will say i felt very clever during this time period, which is a good thing--although i still thought the game was too cryptic.
then i got the sixth note and spent the next ~20 mins trying to parse what the note was trying to say. after doing my best attempt of executing what i think the note was saying, i heard a door open sound. i excitedly walked up to where that last door was only to see it was closed. okay, maybe it's the door i saw back at the start of the level. walked all the way back there, reactivating each door that automatically closed. the door was, again, closed. executed the combo again to hear a door open sound--still closed. then i gave up.
my suggestion: reword the note that says "this door listens to motion" (or something along the lines of that) to instead say, "this door listens to a specific sequence of movement" (or something along the lines of that). additionally, make a few puzzles at the start that are much simpler, and also have some notes that do not have annotations on them.
but also i still have no idea what to do for that sixth note
