Keys remain pressed when player completes level #46
Description
When player input gets removed at level completion (see #31), if a player was holding down a key when they finished the level, the key remains pressed. For example, if the player was holding down the space bar to shoot when they finished the level, the drone continues to shoot until the player moves to the next level; if the player was holding the right arrow key when they finished the level, the drone continues to move right until the player moves to the next level.
