[Easy]:00:24:469 (1) - Suggestion: Remove new combo here and add a new combo over here at 00:25:732 (2) - ?
00:43:416 (1) - You should probably extend this spinner by 1/1 so it'll end at 00:45:942.
02:14:363 (1) - Suggestion: Remove new combo here and add a new combo over here at 02:15:626 (2) - ?
02:33:310 (1) - You should probably extend this spinner by 1/1 to 02:35:837.
[Easy]'s definitely a simple one here. I think you'd be able to raise the HP Drain, Approach Rate, and Overall Difficulty by a small number of ticks without causing any trouble. That's up to you though!
[Normal]:01:20:047 (3) - Jump intentional?
01:26:047 (1) - You can extend this spinner by 1/1 so it'll end at 01:27:626.
Nice! [Normal] seems pretty nicely developed. I'd have to say though, around the end, you seem to have no hitsounds. This seems to contrast the beginning...It'd be best if you added hitsounds after the last break here. I also think you can increase the HP Drain and Overall Difficulty by a small number of ticks as well.
[Okamiroy's Hard]:Hmm...This is a real interesting one here. I like your idea with the spacing and all, though inside it really feels fishy. Sometimes the spacing does indeed get inconsistent. But I don't really know if it's THAT bad, since I seemed to have gotten it myself. It might just be the map is naturally intuitive or my instincts are that good, but I'm unsure. XD
Another thing I'm pretty concerned about is the unbalanced nature of breaks. There's just the whole song with only one break, and that's 30 seconds long. ...That's a pretty long break. I guess it does make sense though, what being the solo and all, but a break that long kills some of the excitement.
Also, why is this difficulty shorter than the others? Do you think you can map all the way to the end?
[sumisola's insane]:00:45:940 (1,1) - This jump is uncomfortable, nya. You have a repeat arrow slider ending at the top, so the jump is kind of awkward, sudden, and really icky. Maybe find some other way to make it sensible?
00:48:705 (2,3,4,5,6) - I don't understand the 1/4 notes here. They seem like they're just...there.
01:23:837 (1,2,3,4,5,6) - Yeah, somewhat the same as above here...
02:00:942 (2,3) - Spacing from here to here seems a little cramped, and not just because of any speed changes or anything. It just felt like that. I think you need a note in between.
02:35:837 (1) - Make this spinner longer (1/1 or all the way before the next note)?
02:43:416 (8) - New combo.
02:51:232 (2,3,4,5,6) - I don't understand the 1/4 notes here. They seem like they're just...there.
02:52:101 (8,9,10) - This spacing is nutty. xwx
Wow! You put your effort here. Pretty cool. Some parts seem totally random...I think I got a bunch of them in my mod up there. I don't really have much else to specify, but I'd like to see this much polish also be put to the easier difficulties as well!
The countdown doesn't fit in this difficulty. Do you mind removing it?
This also might be a little nazi, but what if you capitalize the i in insane?
[[Angel_Beats]'s Insane]:00:35:836 (10) - New combo.
00:56:047 (8) - New combo.
01:16:256 (5) - New combo~
01:27:941 (10) - Remove this note. XD The previous note should pretty much be your ending beat. Speaking of which, because of that, 01:27:625 (9) - should have a Finish.
01:56:678 (1,1,1,1) - Ahh!~ You can't have Spinners that Auto gives less than 2000 bonus to now...Sorry. You have to fix these spinners to give at least 2000 bonus from Auto, remove some of them, or think of another creative pattern.
Crazy ~ I don't know what else to say too. XD
I'm a little concerned for how the breaks are placed. The players' grips might suffer!
However, this is a pretty cool first map.
