00:28:433-00:28:563, change this pls, it's awkward to play; maybe try making it a stair from column 4 to column 1 instead of having the stair on the left side?
02:03:911-02:04:694, you're only using the 3 columns on the left, maybe try moving some of the notes to 4th column too?
02:29:737, shouldn't this be a triple too? considering that the rest of the notes that follow are triples.
03:15:390, same problem as before, trying using all the 4 columns here.
Anyways, fun map; quite hard for a 5 star <3
