Bear with me. >>
Easy:
00:05:27 (4) - Decrease length by a full beat (so it ends on "best")
00:07:75 (3) - Increase length by 1/2 beat
00:28:03 (5) - Increase length by 1/2 beat
00:44:80 (1,2,3) - Here's what I'd do here:
-Delete 2.
-Put 3 where 2 was in the timeline.
-Add 2 more repeats to 3.
I would also consider lowering the slider velocity a bit. Beginners may consider it too fast. Don't forget to double check distance spacings.
Normal:
00:07:75 (4) - Decrease length by 1/2. Add some beats in the space afterwards.
00:12:10 (5) - Either decrease length by a full beat or increase by 1/2 beat. I'll let you decide.
00:18:31 (3,4) - Shift 1/2 beat forward in the timeline. Distance snap afterward of course.
00:25:14 (3) - See 00:12:10 (5)
00:27:83 (4) - Shift 1/2 beat forward, decrease length by 1/2 beat.
00:34:86 (5) - Decrease length by 1/2.
00:48:11 (4) - Delete the repeat. Add a beat 1/2 before 1 (at around the 00:50 mark)
Make sure everything's distance snapped.
Hard:
00:10:23 - Add a beat here (1/2 after 3). Sounds better.
00:45:63 (4) - Decrease length by 1/2.
Otherwise, good.
Also, you might want to consider using the traditional poke ball colors as your combo colors:
Poke ball - red
Great ball - dark blue
Ultra ball - slightly dark yellow
Master ball - dark purple
Just a thought though.
