Good game but one thing – Sharpen Blade Review

Overall I love this game, But there are a few problems with it. Like for instance: After you make the key and open the first chest the game says “ Watch a add to open a better one” but if you press the lose it button thingy (most of the time) it still gives an add, so that is really annoying please fix it.(if that possible). Also, if you break the metal it says FAIL and I get that but when you restart is not just your last stroke YOU HAVE TO RESTART EVERYTHING, which is really annoying so pls add a undo button. P.S. It just needs some changes ?
