I see nothing actually explaining what happens with the varied symbol pieces. Their movements and placement in the hierachy.

Nice and relaxing-styled game.. Since it's mouse only (and why not keyboard? You could assing cursors and a key for click, some people prefer not using the mouse, just an idea..) could you perhaps add a mouse-click (right or middle) for Restart-Level? When you stay away from the keyboard, it's better to stay far away.. Cheers.....

Hi, I would like to translate the game to my language! (Brazilian portuguese).

At some points I would have like to be able to undo my moves, but on the other hand, I think it's a good thing that it's not possible to do that because it forces us to anticipate the gameplay. So I would like to ask to players what you think about that and to dev if it is voluntary to not be able to undo moves, like this function is often implemented in puzzle games of this kind....
