This is my opinion as a novice game designer, and it may seem rude due to its bluntness, but all I want to do is give you advice so that you and your game continue to develop.
The music is good, but does not fit into the surroundings, and we almost do not hear it for half the game. The game really needs better lighting - this is literally half of the post-apocalyptic atmosphere. Our robot has such a short jump, which makes the platforming very difficult, and it seems a little broken. When switching to speed, the robot becomes uncontrollable. It has a really big brake and I fell a few times just by that. The problem is in platforms or controls. Since you have classic flat platforms this doesn't work perfectly. And... Yes, why you make the bridges are purple? That's makes the game cheaper. And for the good tone gamedesign you needed to show the different between instability and normal bridges - player need to feel the different. Rocks and earth in the museum is a bit of a strange decision. But you still have a good cinematic effects, funny interaction between robots and, of course, Amoga Lisa. The game is funny, there is room to grow!
