Hey BMin, sorry for being so late with the mod (1 month).
Alright, so first of all, I tried your BMix difficulty and I have to give you props right away: It's awesome. But let's get to the mod.
[General]
-I understand the whole difficulty name gimmick, but I have to ask if you're fine using DDRX2 diff settings (which I don't know, for the record, I don't play DDR) for consistency and whatnot. This is completely optional, but I wanted to point it out.
-There's a white combo color in there. Not a huge deal especially since he background is very dark, but keep in mind that there are better options. Also, this same color is present twice in your custom color setup. I guess that was intended, but in case you didn't know, you can choose the color of the next combo selecting the note you want the new combo on and clicking the little arrow next to the New Combo button.
-This background for harder diffs has been used several times on maps like ALBIDA and THE LAST STRIKER, only with different colors. Maybe find another one? Up to you. I like the theme with the colors, by the way.
-I'd recommend Tick Rate 2.
[BMix]
00:46:078 (9,10,11,12) - This flows kind of awkardly, in my opinion. I think for this whole combo it would be better to just leave the accelerated spacing and remove the rotation, you'd have very good flow throughout the whole combo.
01:01:862 (3,4,5) - I think this would be better, and sends out the player right into the next combo, giving nice flow:
That's pretty much it. As I said, this is very fun, very esthetic, has a lot of flow to it, and just all around very enjoyable. Bravo.
[BMax]
00:04:132 (2) - I suggest you make this have the same angle as the previous slider, mainly for esthetic reasons
00:10:943 (2) - I think a Ctrl-G on this slider should work quite well (don't forget to do the same for the next sliders if you decide to change that)
00:14:511 (2) - Same as before here. These are sliders so you can have larger spacing than usual on these and still be playable (like the time you used accelerated spacing on these sliders on BMax, now that was great)
00:20:673 (6,7) - Kinda weird to have these so close to the slider. You're building up speed with accelerated spacing, and it just falls flat here. I say increase the spacing and give it a little bit of an angle. x:408 y:372 looks just fine for this, IMO.
00:41:754 (1,2,3,4,5,6,7,8,9,10,11,12) - These 1/3 are not immediately obvious to the player, especially since you're stacking them at the beginning. Maybe just use a slider with a kick instead of these three circles. It will kinda break the pattern but you get great readability (the next ones can stay since the player is locked into the 1/3 rhythm thanks to the slider)
01:01:700 (1) - I recommend this instead (better spacing and also for reasons quoted in the BMix diff)
01:38:835 (1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,7,8,9,10) - I really don't like this ending very much, it feels very dull. I'm sure you can find something else to do with it.
[BMed]
00:04:132 (1,2) - I'd suggest making this into a 1/1 slider and keeping the (2) because the rhythm is kinda awkward.
00:09:322 (1,2) - Same, of course.
00:14:511 (1,2) - Once again.
01:22:619 (6,7,8,9,1) - This looks very ugly. I'm sure you can arrange this to make a better shape (don't focus on keeping distance snap on at all times, such a small difference shouldn't matter)
[BMin]
Overall, this has quite awkward rhythms for an Easy map. I know that on such a song, it can't really be helped, but try to guide the player as much as possible.
00:02:349 - Add a circle here to guide the player. The previous pattern you have makes it unclear when to hit the note.
00:07:538 - Same here.
00:08:349 (5) - I would make this into a 2-measure slider to guide the player into the next one. Circles work also.
00:12:727 - Once again.
00:59:916 (1) - Why not making this a spinner? It fits, and you had one here in BMed.
01:34:078 (2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,1,2,3,4,5,6) - Once again this feels quite dull. Since by now the player knows what to expect of the song, I'd suggest turning these into 3/4 sliders with a returnarrow, so that they flow nicely.
Although the map is rather standard in the easier difficulties, you managed to make a very good Hard and Insane. I'm definitely going to enjoy this once it's ranked. Good luck!
