When graying out blue or white arrows, you lose the information, bc they all appear almost the same. The difference really isn't clear enough when grayed out. It would be nice if we could cross out squares in white or blue, and if the graying out of the clues showed more clearly what they were. (maybe reversing the colors instead of just greying out). I agree with the other commenter calling the hint system too clunky, I'm also not a big fan of the drag and dropping in general, makes the game feel very heavy (even just removing that line would make it feel better I think)
I really enjoy this game, but there needs to be a more solid save system. I've just lost all my progress after getting halfway in the normal levels. Now I need to redo all the easy ones, before I can even get started on the normals again. The lock on the difficulty levels is in my opinion totally unnecessary. Besides that I absolutely love this game!
