This is my first original map.
The song is called”Let’s Have a Mammoth” by Carlos Hakamada. (in Japanese マンモスをそだてよう by カルロス袴田). My favorite song.
I started mapping in January 2021, and have made many mistakes and given up on many songs(mainly because of BPM mismatch).
But finally, I was able to complete one.
The song is 2 minutes long, and the difficulty level is only Hard, but I think you will enjoy it.
