I've completed every puzzle in every pack but the final achievement isn't unlocking, any suggestions?

How come it's no longer on the play store? I can still play my install, but... is there anywhere else I can download it to my phone if for some reason I need to again.

Game are closed after starting. Thanks Dev for adding achievements and making your game unplayable. (Steam should ban you all ♥♥♥♥♥♥♥s...) - sorry fot that, but I was really dissapointed because of another game with achievements impossible to get... <3...

Nice game! If you want, I would do the translation of the game into Czech. Send me or upload somewhere resources..

I have a few questions: 1. Can you find one that overlaps another that's already been discovered? 2. Is there more than one solution to each puzzle ? (Including Random Levels) 3. Can the size and complexity of the Random Levels be defined?
