First of all, I would very strongly suggest not looking up solutions! I know it's tempting, but I promise that all the levels in the game can be beaten with persistence (even if lots of them are mean). General puzzle-solving tip: work out what you can't

I've completed everything else in the game, but this one seems beyond me. It took me long enough to figure out Nova 7, now I feel like I'm just banging my head against a wall for no reason. I would be interested to hear if anyone worked this out on their own. Steam global stats say that 0.2% have completed it, but I'm not convinced they didn't just hack the achievement....

I'm hitting a hard wall here. I'm sure there's some sort of weird solution, but this looks mechanically impossible every way I can twist it. Anyone cleared this level?

Which one did you find to be the easiest? I didn't need any hints for completing it and must have finished it in 20 mins around.

Don't see why it doesn't have it..
