This is pretty solid. You were smart to pick a game with limited scope, by the way- it seems like you were able to make a much more polished game as a result.
I like the way the mines feel, by the way- what sort of behavior are they using? I will hazard a guess and say they move straight toward the robot at a velocity which increases with distance (and I'm guessing there's no acceleration?).
I like the "ouch" effects, by the way. Oh, and the tension of approaching a mine as it's getting ready to explode is fun.
Nice job, thanks for making this.
I was idly wondering, do you think it would work to have the robot swing in a fun swishy way instead of popping between angles as we move left and right? I could see little floppy legs being an awesome touch too :D.
Oh, and if you ever want feedback or help testing, I'd be happy to help. I'll be around the #ludumdare channel.
