Enjoyed the game quite a bit! (Big fan of puzzle games here!) It’s quite ingenious how the wobbly lines make an otherwise static game feel so much more dynamic! With a few minor improvements and a few more puzzles, I can see this becoming a fun game to play on the phone!
Regarding the theme, … it feels like a missed opportunity to work in imaginary numbers. https://en.wikipedia.org/wiki/Imaginary_number :-)
