I Wanna Defeat the Seven Colors
Stage reviews are in order of in-game difficulty ranking:
蒼羅's stage (blue) was the easiest. I liked the visuals, and the music was alright, albeit a little repetitive since the track is no more than 30 seconds long. Has water physics on the second screen. All in all, this was a pretty good stage; had decent level design and some pretty cool jumps.
とも's stage (red) was also pretty fun. This stage was riddled with both some really fun saves and some really annoying saves. The visuals are a little much, but the music was really good. This one also had some really cool jumps.
SAKI's stage (yellow/orange) is probably my favorite. The visuals are kinda gritty, but in a way that I like, and the music is also really good and fits really well with the graphics. The level design is decent, and there are some cool jumps here as well, and a gimmick of infinite jumping and triple jumping is used in the last one or two rooms. This was about the same difficulty as とも's stage.
瑪瑙's stage (green) is ranked an easier ranking, but I personally think it should be ranked a lot higher. The segments here are longer and can be really annoying depending on whether or not you're good at playing upside down. Though the segments had really cool ideas, it was a bit much, especially seeing that every other save has either a downwards or an upwards plane to do.
あお's stage (blue) is an L-needle like stage, which makes some sense for him to do since あお is the maker of the original L apparently. This stage's rating should be switched with 瑪瑙's stage, since this was so much easier to beat IMO. I liked this stage, though I know a lot of people hate L games in general so...
闇空's stage (purple) is by far the hardest IMO. It's hard to find a save here that doesn't require jump cancel or one frame; the second save has the final jump of Insanity Ultimate plus some more jumps after it. This one was extremely overkill IMO, though I liked the visuals a bit.
初見's stage (yellow) was the second hardest for me. This one was interesting; the first screen starts with a somewhat standard jump, then starts to get more interesting as you progress. The top portion has a pretty cool idea of rotating shurikens that you have to squeeze around and between, though it can get a little annoying. The second and third screens use triple jumps, and, although the idea for each jump in those screens were kinda cool, it was also really annoying.
I'd recommend this to people who like collabs in general and want a REAL challenge in needle.
Would definitely recommend if you want to grind some hard needle.
If you wanna play it you gotta be really good at jump cancelling and really skilled.
