A cute puzzle platformer. The original song is really good! The pixel art is nice and I like the little robot character and its animations. I like the addition of dialogue from the civilians you rescue.
The jump between platforms after the third or so checkpoint is really difficult even when I hold the space key down to jump higher. The physics of the push blocks are a bit wonky and tend to get caught on each other and the terrain. This made it especially difficult on the part where you push the boxes into the water.
Overall, nice job!
