Mod time.
Normal
00:34:63 - I suggest a break.
00:36:31 (1,2) - Whistle hitsound.
00:43:60 - Break.
00:52:29 (5,1) - Instead of this, I suggest making a slider that lasts from 5 to 1 (thus removing the new combo).
00:58:73 (6) - New combo (argh I've said this so many times to Skyripper earlier orz)
01:06:02 - Break.
01:12:19 (1) - Not a mod post, but NICE BOAT... I mean NICE WORK.
01:22:56 (1) - End point remains, but the start point should be 1/2 a beat after the last note of the combo.
01:30:69 - Add one more note, then add a break after.
02:17:22 (5) - New combo.
02:19:75 (1) - I suggest finish
02:26:19 (7,1) - Add new combo at 7 and remove from 1.
02:39:65 (1) - Again, nice work.
02:50:02 (1) - Basically, it's the same issue as 01:22:56 (1)
03:09:36 (1) - Remove the new combo.
Hard
00:33:22 (4,5,6) - between 4-5 and 5-6 the gap is slightly different. Please adjust.
00:36:31 (1,2,3) - Do an INIS-style here lol. Place this so it's symmetrical with the slider below.
00:42:19 (1) - Remove new combo.
00:52:01 (6,1) - Remove new combo from 1 and add to 6.
01:22:28 (1) - Up to this point I realised why you wanted that spinner to start from this spot, but... if you would pick up on my suggestion, may I suggest starting 1/2 a beat from the last note and end at the same spot? Yea, it's something like the modding as above.
01:33:21 (3,4,5,6) - For this one, I suggest a "whistle finish whistle finish" streak. Smacking finish 3 times in a row seems a bit jarring, but again this is a suggestion...
01:41:06 (3) - Be daring here. Place it so it's equally distance from 2 and 4 yet creates a small jump of its own (which means moving this more towards the right and lower)
01:46:11 (1) - Remove new combo.
01:52:00 (1) - ^
01:57:60 (1,5) - Remove new combo from 1 and add to 5.
01:59:56 (1) - Remove new combo.
02:50:02 (1) - Spinner issue same as 01:22:28 (1)
02:57:03 (1,2,3,4) - I suggest a bit more boldness here. A square-shape series of jumps, perhaps?
03:10:49 (1) - Remove new combo.
03:15:81 (9,1) - Add new combo to 9, remove from 1
03:19:46 (1,3) - Remove new combo from 1 and add to 3
03:25:06 (8) - I admit, this is very minor, but if you're aiming for a square, I think you'll need to adjust this slightly orz
03:42:72 (6,8,1) - Remove new combo, add to 6, and make it such that there's a slider from 8 to where the old 1 is.
03:48:33 (1,1) - Remove both new combos and make a slider from the new 7 to the new 8 (after you removed the new combo)
03:54:50 (1,4) - - Remove new combo from 1, new combo at 4
03:56:18 (8,1,1) - Remove both new combos and add one at 8.
03:58:70 (5,1) - Remove new combo from 1 and add to 5
04:00:38 (5,1) - Remove new combo from 1 and add to 5. Uhh, or ^. Damned.
04:08:51 (1) - Remove new combo.
04:13:56 (3,1) - Nasty move. Sure, this DID hit the auto 300 + 2000 bonus criteria, but this is horrible because the last note was 1/4 away and it lasts so short. Very likely to throw people off bad. I suggest shortening 3 by 1/4 at the very least.
04:16:36 (2,3) - Yawning gap. Make a slider and cover this gap.
04:09:91 (3) - No overlapping. Re-design so the start/end doesn't overlap, if possible.
P.S.: This song was one a friend and I used to sing over MSN. It's pretty sweet if you ask me.
