X is really excited about getting into video games, but she tends to forget to move when attacking or to attack when moving.. also (a huge problem in isometric games like Bastion) she tends to only press one WASD key at at time, moving in straight lines rather than continuous paths.
What would be a good method or game to teach her to rest her fingers on the WASD keys and use several at a time, while also not forgetting to attack?
