I like the game a lot. The only game on this site, i play regularly, since i found it.
Sometimes a "balanced" pattern is harder than a "brutal" one, that's sometimes annoying but i don't think you can do anything about it, i guess it's just math.
But i would like to have an option to restart the same game again. As far as i understand, you can't do that right now. A restart gives you a new starting pattern. Maybe you could bookmark starting patterns to play them again later (that's probably too complicated to implement).
Restarting the same game, would be awesome, i think a lot of people would appreciate it.
