Ooh! One dimension! Interesting.
I think the +/- keys are pretty useless tho.
I think you could make more puzzles and more elements and turn this into a nice mobile puzzle game. I sense potential.
Thanks! I think I pretty much did the puzzles I could with the mechanics I made, but maybe I'll do something more with this some day.
And yeah, changing the line thickness does nothing for gameplay, it's purely there as a graphical preference.
