Played the first few walls of this. Having the first wall wait while I worked out the controls was a smart touch. I bent the wire the wrong way, the wrong segment turned red with an arrow pointing at the key that undoes it, and I understood the undo rule without reading anything.
Clearing a wall, watching it shatter and seeing the streak tick up to x1.25 feels great.
One small thing: the NEXT preview in the top corner was easy to miss at first, because my eyes were on the centre of the tunnel. A brief highlight on it during the first wall might help new players notice it.
Nice work on this one.
