Jiyuu's Test Track is an early custom track made by Jiyuu. It was originally a way for the author to test his workflow before creating more complex tracks. The track has a similar design to SNES Mario Circuit 3, which this track is inspired by a lot. The author decided to release the track publicly so that anyone can play it. For v1.0, the aim was to lighten the track as much as possible. The track was formerly known as "Jiyuu's Circuit".
