First off. This Chart has a major issue With its offset. Currently it is left at 0:00.000 which is incorrect. Arrow Vortex has this really cool feature if you go to Tempo -> Adjust Sync (shift + s) where you can have AV automatically find the BPM and offset for you. Its not perfect but it does a good job.

Additionally because the sync on this chart is off, some notes have been moved to be more in line with the audio, while some are still synced to the bpm causing incorrect rhythms to appear.

I would recommend against using 50 bpm for a song. 200 or even 100bpm would work just fine and give you more room to place notes more accurately as well as a more readable chart.

I found numerous errors in the charting of the file. On many occasions notes are missing from the chart that are in the song. Possibly caused by the offset issue. Notes such as 0:04.950 are left uncharted.

There are many issues with Chord Consistency in this chart. It feels a bit random what size of chord each note is given. Sometimes the same sound will be given a jump in one section, but a hand in another. Its a good idea to create "rules" for your chart that you can use to create a more consistent experience. Something as simple as Kick=Jump Cymbal=Hand can go a long way.

The difficulty of this chart feels a bit all over the place. There are some sections with easy holds while others are much harder than the rest of the song such as the one hand trill at 0:27.400. While a chart doesn't need to have a consistent difficulty across the entire song, its important to make sure its still balanced throughout the song, with nothing too difficulty, and nothing undercharted.

Judge Score: 6.00 - Rejected
