Level A.7 seems to be impossible to solve. You obviously need to get the left movement arrow to the hole to allow the user to move to the left. There are not enough arrows to cause movement around one of the black columns and movement across the purple arrows causes the character to not be able to move, which causes it to be impossible to be able to use the purple arrows to get above the left arrow block. Since there are no ladders on the upper side of the raised area on Level A.7, it seems to me that there is no way to get the left arrow to go downwards
