As Afely mention, the art is great and increasing the speed of the game would probably make it more fun. I'd only like to add two small things regarding their comment: the robot felt often kinda dumb, as they went to far away rocks when there were others way closer. I also wish the "Heal player" and "Heal Robot" upgrade would do something when the player or robot has full health, respectively, or maybe not show up at all.
Weird win screen SFX lol:
