How does your submission match the theme?
It's main mechanic is about doing two things at the same time. If the Player wants to shoot, it will also walk, and vice-versa. There will be always some parts in the level design that would need to make the "right choice" because of this, since they may not want to walk to a certain direction (because of a Hole), or don't want to kill an Innocent or something alike.
The act to recharge the ammo also have a secondary effect, that is to pass a turn without moving. Which often comes handy.
In the last two stages, the Player can control more than one character at the same time (they can control the Main Character and some Special Enemies), and with that, the obstacles of Hole and Wall were giving a new purpose. Since the Player needs to kill all enemies, they can make the Enemy jump to a Hole, or make the Main Character face a wall while walking, to align both characters, and the Main Character can shoot this Special Enemy.
