There are some really nice elements in here. The robot looks super slick and I can see the independent movement of the parts, that's really cool. The particle effects are also super satisfying and just fun to watch. I was also super drawn in by the simplicity of the title card, very nice work.
Unfortunately, I struggled a lot with the movement. I saw in the comments below that you wanted to give the sense of a diminished character who becomes stronger, but I ended up just overcoming this by holding down shift the whole time I played. It's definitely commendable to reinforce thematic elements with gameplay, but I think in this case it didn't feel great and I had to overcome it by making the game less enjoyable by dashing at breakneck speed everywhere...).
Secondly, the map was fairly difficult to navigate. I know that if I get into the next room and drop down to the left I'll encounter a boss, but that was about as far as I was able to get in terms of building a mental map. There weren't many places where I could go, "Aha! This is THAT part of the map, I'll remember how to get here in the future."
Also as has been mentioned, the parallax was pretty rough on the eyes.
Overall I think that you did a good job of realizing what you wanted to with the robot, and the amount of work you put into it showed, I look forward to seeing what you come up with next time if you participate in MVM XVI!
