edit: found a way to solve it in 6, but not in 4
—-
Edit: and the right answer was so obvious, too
I'll be particularly curious to hear the pattern(s) in how many solutions there are, and/or the probability of a random board being solvable.
The haptic feedback on mobile is really on point in this implementation.

Edit: limiting it to square flips was a great idea. There are just enough moves to make the answer non-obvious (after lvl 15), but not so many possible moves that you get overwhelmed.

Edit 2: I just remembered I made a similar "game"[1], where you select columns to XOR with other columns and try to reach the target pattern. Use the scroll wheel and shift+wheel to change the pattern and size.
That was actually part of a real research project in optimizing circuits for computing binary finite fields, where the "game" was a sandbox to try different algorithms. The best algorithm was actually found by someone playing in this sandbox and coming up with an efficient strategy.

Although interestingly some other people in the comments here say they liked how the progression goes.
And that's an interesting little game you made.
And I spent quite some time creating an algorithm and solver to find the par for Unflip. I'm planning to release a blog post about it soon
