Game play speed up

[Scherlac]

Tapping on the figures and changing the color is somewhat slow.

I need idea how to speed up

• Swipe right to "repeat" the color placed on the left next to the current position?
• Swipe up/down to change the color back/forth?

Have some more idea:

• Double tap on one of the previous line to copy
• Tap and hold to show a color circe around the piece:

I already prepared the SVG for the color circel
