Good game, badges would be nice, and its a shame it assumes u finished, and wouldnt let u make the copy perfect, as soon as u hit the target. There could be a harder lvl in which u could use only a limited number of overpainting and a time limit :)
I relly like that - used to do loads in printed version. The game has some major annoying flaws.
Sometimes the numbers do not fade away even if the box has been coloured (and both sides have been crossed out) - which made me make mistakes. It would be useful to have a possibility of fullscreen as numbers were illigible on top of the coloured boxes, or dissapeared in the row wasnt highlighted - again without that clarity I made annoying mistakes.
And the last thing- badges would add great value to the fun.
I like that game, hope the next version will be improved :)
