>sometimes you have to turn off a cell or two to make one of the next bricks fit.
Do you really think that someone can get to level 27 in your game if they don't know that?
I only managed level 27 on the 8th try. This is frustrating for me. Before I managed more than 20 levels on the first try. Now I am in level 29 and failed on third try. The attempt in the image cannot be completed successfully.

The game shows 3 bricks but I can only take two of them. It's incredibly frustrating when you see the brick that could solve the level but you can't use it. The game is too hard and the random factor is too big. The game should provide one more brick. Especially in the Easy (Leicht) difficulty level.
