I think that the puzzle requirements should be moved to the left hand side of the screen and arranged in a vertical manner. I personally do no use that space of my screen very much but the area that they are currently in I do use (or would like to).
Also on levels with more then 4 requirements like “The small hairpin level 3” the last requirement is covered by the energy box.
Thanks for the suggestion Matt! I’ll bring it up at the next Eterna Team meeting. I have placed it as a feature in our bug tracker at #148.
