After accessing the secret level from level 51, going to the pink square (after visiting all available tiles) it takes you to level 52. Is that the right way to complete the secret level? Because the achievement did unlock by doing it that way. All the other achievements worked though....

I've completed the game, reset it, completed it again and started with green yet again, but I have not gotten the Restart / Start Over Achievement. How do I get it?

I started up the game, did the first puzzle, but nothings happening after that. Is there some other button I'm supposed to press or some sort of action I'm not doing in the game? I'm just stuck on the first puzzle but I lit up all 10/10 squares...

I have all others and it would be nice to have 100% completion

I enjoyed the game but... I'm stuck on level 20. I've cleared all squares but the game doesn't take me to the next level. Please fix it.
