Don't get disappointed by the following wall of text, ok?
First off, no need to have the tags "puzzle" "bobble" "zuntata", since all these words appear in the source or artist fields.
Something about some of the hitsounds doesn't sit right with me...I'm not very good at modding hitsounds, but at times it sounds like you're using a lot of different sounds in a short space of time, and this variety isn't needed? Something like that. If you can, find someone good at hitsounds and ask them.
Now, then:
vs. Monsta (Normal):Switch the positions of 00:39:035 (1) and 00:39:785 (3) to have 00:39:035 (1) closer to the end of 00:37:910 (4) - right now, it's a larger jump than expected (not that I can't clear it, but let's make it more appropriate for Normal).
00:45:160 (1) - Make this start at 00:45:410 instead, you'll get the effect you want (to make the spinner fade in as soon as you end the slider) to look better. Same goes for 01:35:910 (1) (make it start at 01:36:035 instead) and 01:55:660 (1)) ( make this start at 01:55:910 instead).
In all, the map's spacing is pretty inconsistent. It usually goes between 1,2x and 1,5x, which in itself is kind of iffy but not too bad, but at combos like 01:15:035 (1,2,3,4) and 01:21:035 (1,2,3,4) it's suddenly 0,6-0,8x. At 01:44:910 (1), it uses 1,0x while the combo before uses 1,4x. I'd like you to at least fix the most blatant examples like this, but I also recommend picking one spacing value and using it throughout Normal, if you don't mind. It may be a lot of hassle to move everything around, but it will make things clearer for the player. You can still break spacing a little to pull off aesthetic things like 01:13:535 (1,2,3,4,1), but don't go overboard. Try seeing if you can still make it look pretty while following one spacing.
vs Dreg (Hard):00:45:160 (1) - Make this start at 00:45:410 instead, you'll get the effect you want (to make the spinner fade in as soon as you end the slider) to look better. Same goes for 01:35:910 (1) (make it start at 01:36:035 instead) and 01:55:660 (1) (make this start at 01:55:910 instead).
Again with some inconsistent spacing, like 00:29:660 (4), which should be farther. Another example you should definitely fix is 01:28:160 (2,3,4), where 2 and 3 are stacked away from 4, although 3 is closer to 4 than it is to 2. In 01:36:035 (1,2,3,4,5,6,1,2,3) - the spacing starts larger than 2.0x from 1-4, gets even bigger at 5 and 6, but then drops to about 2.0x for 1,2,3.
I guess what I'm generally saying about spacing in this beatmap set is that it's good mapping practice to almost always use consistent spacing within a single combo (with possible rare exceptions like 01:54:035 (1,2,3,4,5) for the eye candy, but then again, how about making them into a pentagon?). In Hard and above difficulties, you can do jumps or anti-jumps between combos, but even then, things like 01:36:035 (1,2,3,4,5,6,1,2,3), where the spacing goes from 10 to 12 and then to 8 in a very short amount of time, are still too confusing, even if you make the parts where the spacing changes new combos.
01:22:410 (3) - This could be directly on top of the slider like you do elsewhere in the map. It's more consistent aesthetically that way.
01:40:160 (2,3,4), 01:46:160 (2,3,4) - If you don't mind, separate the 2 from 3 and 4.
vs. Mecha Warrior Bubblen:00:52:410 (3), 00:59:160 (3) - These are a couple of examples of jumps that are just fine, as long as you make those circles a New Combo.
01:20:660 (4) - Put this on top of the slider's end for aesthetic consistency.
01:55:660 (1) - Like in the previous difficulties, make this start at 01:55:910 instead.
To reiterate: spaaaaaacing. I know the song by heart, and the spacing threw me off at some points. That can't be a good sign!
Hang in there
