- It must be an unpublished BMS. There is no problem in converting the previously announced songs to BMS.

- BGA and similar files (BGI（BGA with only one illustration）, background image, banner image, title image, missed image, etc.) are strictly prohibited.
* It is permissible to specify the BGA definition in the musical score file in advance for reasons such as adding a BGA file after the event ends. Also, as a special case, it is possible to use an image filled with color code # 000000 as a BGI / banner.

- Please include one or more musical scores that can be played normally. If you have a musical score that uses an audio compression format (ogg, etc.), WAV extension definition, long note, stop sequence, or other special instructions that only a specific player can use, be sure to specify the recommended player.

- "Arrangements that give some visual effect that does not directly affect the game" in the music lane, such as mine animation and score arrangement like letters, are not recommended. We recommend works that evoke something from the sound and musical score.

【Impressions】

- Although it is not compulsory, please set the quality of the "normal" level you think to be 0pts, and score in the negative direction if the evaluation is high, and in the positive direction if the evaluation is low. (Maximum: -100pts, Normal: 0pts, Minimum: 100pts)

- Anonymous impressions are also OK.

- There are two types of check items such as "クラい!"（Means ”dark!”） And "マブい!"（Means ”the light is dazzling!”） As an evaluation system.

- "クラい!": A bonus index attached to works that you want to listen to in a dark place or feel darkness.

- "マブい!": A bonus index attached to works that you want to listen to in a bright place and feel the brightness.

- At the time of impression, you will be asked to select either "クラい!" or "マブい!" (Neither is selected). These will be displayed after the evaluation period ends.

- Bonus points will be given to the points earned for each number of "クラい!" And "マブい!" In addition, additional bonus points will be awarded for each additional number earned.
* the score of "マブい!" Is set lower than that of "クラい!".

- In addition, for "クラい!" And "マブい!", The specified bonus points will be added to the works with the highest number of acquisitions and acquisition ratio rankings.
