Holding the Sonic Drop button doesn't constantly drop the piece at 20g

If you can reproduce it, write the steps here. If you can't, try to describe what causes the unintended behavior, like pressing a key/button (Details Here):

1. In Techmino, hold the Sonic Drop button (and don't release it)
2. Move/rotate the active piece into a place where it can fall
3. Notice that the active piece doesn't immediately fall at 20g, unlike in TGM3.

oh at that time I thought "sonic drop" is a press-only function so I didn't implement this
