Interesting puzzle-like turn based game. I think it has great potential, but it is not there yet for me.
More than anything I felt like I am just delaying inevitable death. The fact that both me and the enemies moves by one square every turn means you are either one space short for hitting the robot or you will get hit first and then you can destroy him. I feel like simple "pass your movement" action could solve some of this.
I like the robots that shoot other dead robots. It adds some of the much needed complexity. It would be great (and what might be another solution to the issue I have described above) if the projectil could also hurt another robots. It could create some strategy level in positioning enemies in between you and the projectile.
Waiting for enemy movement felt little too long.
Art is simple but functional. Menu UI feels fresh. Music fits the game well.
Even that I describe some of my issues with the gameplay - you did a good job!
