Neat concept! I like the idea, and the animations feel quite smooth. There are some issues though, mainly with understanding the controls. It is unclear how to select which of the commands you are editing, and unclear how to begin shooting and moving when commands have been entered. In addition, a grid may make it clearer how many movement commands are needed to be in front of an enemy to shoot them.

I hope that you will find time to polish this game, it's a really nice idea!
