The robot's movement feels good, both fast and smooth. The way you can push the civilians around feels quite good too, and from a technical perspective it works well.
Personally, I didn't manage to find much depth in the gameplay -- I could block the shots, and push people out of the way, but neither option evolved much and it was difficult to do either consistently. I'd be more motivated to practice and experiment if there was a higher ratio of gameplay time to waiting time. I also wonder if it would be feasible to control the difficulty curve slightly more by (for example) giving more warning time on each shot, and reducing it as the player progresses.
I also couldn't see the relevant of the rope - you can push the civilians around individually, and the rope grows to whatever length you need, so I found it slightly confusing.
Overall, though, this was interesting, and it's great to see a complete game made in just 48 hours. I've never seen gameplay like this before, which is cool. Well done!
