Interesting concept! I ran into a bug where after hitting the back button to return to the main menu I wasn't able to start a new game. The music it made was nice. I wish there was a way to delete a peg without having to reset the level.
That menu thing, I'll investigate and fix. The undo button would've stopped players from trying new solutions out, so i provided a reset button instead. But i will look into it.
Please do provide rating in GMTK Game Jam, as that matters the most for post Review period.

Thank you for trying out my solo venture!!
