Hey guys, party pooper is coming (/ovo)/Hello, i'm sorry about it, but this map contains unrankable stuff, that's why i'm here
SkinningGameplay elements must be visible. You cannot make any element that will impair the playability of the map invisible as it will make the map unintuitive or even impossible to play.
Your 300 hitbursts are invisible.
Hitbursts must be clearly distinguishable from each other (e.g. 300/100). The best way to ensure this is to use a different color for each hitburst. Otherwise, the player won't know if they're hitting beats accurately.
50, 100k and 100g look same. more than that they are totally not informative. with low proсent of dimming they are almost invisible too. Add here your flashes and effects in SB and hitbursts are unreadable at all.
Do not make any essential gameplay elements larger than template skin dimensions (especially for combobursts). Larger elements may effect gameplay performance, and thus should be avoided. However, any elements that do not directly effect gameplay (e.g. pause-back, play-skip, etc.) may be slightly larger if a legitimate reason is given.
Actually 50/100k/100g hitbursts are larger than notes and it's unrankable too.
When skinning gameplay elements, complete sets of elements must be skinned. For instance, if you skin hitcircles, you must include a hitcircle.png, hitcircleoverlay.png, approachcircle.png, and a slider border color (this can be done by adding the line "SliderBorder: 255,255,255" (using RGB values) under the [Colours] section of each .osu file).
Where is "SliderBorder" line? you missed it.
You use pure white combo colour(255,255,255), which is still unrankable.
For breaking 5 rules (meh), i sadly have to disqualify this map. Rest of suggestions will be added later to this post._____________________________
Addition:
SByour SB can be tweaked. now it has overloads, it can cause problems to users with weak machines. These overloads are not so big, but if you have time, try to turn off unused layers in critical moments. Thank you~
00:00:199 - huh, i think this movement is not supposed to be here
Beginner01:52:882 (2,3,1) - i'm not sure it's the best way of mapping for part, where timing is changed. Sliders are more "freindly", i'd recommend to use sliders here.
Standard01:53:649 (1,2) - same as in Beginner, hardest place mapped by notes. Up to you of course.
