The picture above is a mock-up I made for the turn-based battle system I had in mind for Letter for Mimi 2. On the left side will be the players sprite, and the enemy on the right. At the bottom there will be a menu/dialogue system that allows the player to select attacks and it will show the feedback of the attack and the attack of the enemy. The two bars are for the health points and the energy points. Energy will be used to determine which attacks you can use, stronger attacks will require more energy.
