This game illustrates why I don't play piano.
The two track system is really creative. Gigi's hitbox was a little unclear to me and I found the control scheme for Gigi challenging, I kept pushing A/D relative to the lane that the car was in rather than ASD based on the track. Once I started to get the hang of it though pushing the keys in rhythm to the track felt really good, and the songs are great. Nice work!
