Platform: Mobile - Android & iOS (will add flair)

Description:

A connect-the-dots puzzle you can't brute-force. Most flow-likes can be beaten without thinking: hug the border, draw wide paths, fill the leftover space. My generator bans both tricks - no line may ever occupy a 2x2 block anywhere in its solution, and in the harder sets both endpoints are buried mid-board, so "edges inward" has nothing to start from. Every Extreme level is machine-verified to have exactly ONE solution. There are 18,000+ levels across relaxed and brutal modes, and every mode is unlocked from the first second - no grinding. The clip is one continuous take; that board took me 13:49 on my own game. Transparency for rule 4: the background theme art is AI-made. All code, level generation and verification are my own work.

Solo developer - design, code, the level generator, and the solver pipeline that verifies uniqueness. That's where the past year went.

I played 10+ Flow-likes and none of them made me think, so I built one where every level has exactly one solution

I've been playing this genre for years. Outside the original, almost every clone lets you brute-force levels by filling empty space — there's no actual deduction happening.

So I spent the last year building the game I wanted: every level in the Extreme modes is machine-verified to have exactly one solution, and there are no filler cells to mindlessly drag through. If a route "looks right" but is wrong, the board tells you by not closing.

Some of my own Extreme levels genuinely make me rage, which I take as a good sign.

Not trying to spam — I'd really like feedback from people who actually finished Flow Free and wanted something harder. Happy to answer anything about how the levels are generated and verified.
