Cool game! I included it in my LowRezJam compilation, if you’d like to take a look :)

Graphics and sound work great. Some animation in the "beam" and maybe some particles/effects when it makes contact would really help make it pop. Your music really compliments your pixels and game style. I would have preferred the gameplay to have been a little faster. Increase the robot's speed and decrease the amount of damage necessary to break though maybe. I think the recharge versus frequency could be balanced a little more. The distance/spacing between them feels more random than scaled with how far you've traveled. Fun little one button mechanic that fits within the resolution limitation well. Good job!

Great graphics and sound, but I felt the game-play was a bit minimal.
