00:00:835 (835|0,1263|0,1692|0,2120|0,2549|1,2977|1,3406|1,3835|1) - if you want to use stacks of notes in a row it's best to alternate hands (so I think one of these should go to to 3 or 4). It'll be more comfortable for beginners. Similar situation here: 00:04:263 -
00:07:906 (7906|0,8335|0,8763|0,9192|0) - Hiiiighly recommend not using 1/2 LN jacks on off beats in an easy difficulty. It's going to be really hard for beginners to time those.
00:20:120 (20120|1,20549|3,20977|1,21406|3) - you should spread these out a little more. I don't see a musical reason to keep them like this and you spread out notes at 00:26:549 (26549|1,26977|3,27406|2,27835|0) -
00:26:549 (26549|1) - but you should delete this note for consistency. (you didn't add a regular note at similar spots in this section). Also delete this: 00:40:263 (40263|0) -
00:24:835 (24835|2) - The end of this LN should be moved up to 00:26:549 - for consistency (see 00:17:977 (17977|0) ) -
