I've seen your playback now XD using only mouse to control may seems quite confusing.
About controlling, there's actually only a 2-direction control, which is left and right.
Actually "touching screen" was designed for celphone playing . For keybaord playing there's A/D or arrow keys (only left/right) for it._(:3JZ)_
If you have a joy stick, you can also use left stick to control it, no strength sensing tho (haven't tested because I don't have one XD)
Thanks for playing anyway 😁
