I love the opening sequence and the music. Great job!

I thought the opening sequence was great. Seeing each part fall off gave me a really good sense of what my goal was, and the bat flying off with a bit at the end made me laugh.

The bad points are standard game jam platformer things. Add some coyote time so I can jump off the end of a platform without pixel-perfect timing. Make the hitboxes on the player and the spikes bigger than the art, so I can have a near miss. (http://devmag.org.za/2011/01/18/11-tips-for-making-a-fun-platformer/)

The sheer number of robot bits was impressive. I particularly liked rolling over to my legs at the very beginning, and getting my head back.

Love the visuals and the story telling with visuals and not words.  The platforming is frustratingly hard for me. I think the picking up the bits of the robot is a very organic way of the character gaining abilities.

Short but fun game! The continual expansion of the robot's movement capabilities means the gameplay challenges remain fresh. I thought the grappling hook worked remarkably well.

The music is upbeat and pleasant at first, but felt repetitive after a while. A bit more visual polish would be welcome, also. E.g., some animation on the main character and a little bit more variety on the backgrounds.

It's a short and fun metroidvania experience. I really liked the concept of the robot putting itself back together as a way to gain abilities. 

The gun ability is underutilised, as there is only one cracked wall that needs to be destroyed in order to progress in the game. There could have been more enemies to fix this.

The movement feels sluggish and hook is way too slow. On the other hand, the moving platforms are extremely fast so it's really hard to land on them properly.

Overall, it's a really nice game that needs a little bit of polish. Keep up the good work.
