Is it a pattern ? Is it a planet ? No, it's a god damn IQ test in disguise...
That was super original, my only complain is the lack of preview before selecting a cell. But there is the undo function to make mistakes so that's ok. Cause sometimes, it feels like I bruteforce the thing instead of using my brain. Maybe adding a preview and forcing the player to make it to the end in X turns could be a good addition, I don't know.
The fact that the game doesn't spam you with a new tutorial when you launch it a second time is a nice detail too.
Also the infinite emptiness of the void was hard to hear for me, so I put some dark ambient while playing, and it fit perfectly, providing an instant buff of +10 charisma to your game.
Nice job here
