There's definitely a nice basis for a game here, and the simplified controls, if a bit janky at the moment, seem like they could go somewhere if there was more reason, or ability, to plan multiple attacks at the same time.  Possibly a delay on attacks, picking a location to attack, stuff like that could lead to some interesting plans and setups for causing chaos.

Speaking of the janky controls, the selection is a little weird to deal with since there's not a clear indication of which unit you have selected, unless you specifically look to the right of the screen and or move said unit to see which one is moving with you.  So I feel like some sort of circle around it etc. would solve that issue pretty quick, it would just make it clearer which was selected etc..  As well some sort of pause while deciding actions would be helpful, just to help plan out a bit more.  Assuming you did go more complex with the actions you can do.

 Overall though, this seems like an interesting basis for a unit based chaos game.
