This is a really neat idea, but the game feels really hard. I'm not sure what pieces are good for what, or how you can place them. It seems like they always appear in the same spot? I'm honestly not even sure how I completed the first level, my tripod is tipped over and the spider is still there.
I think with some feedback to what each piece does as your choosing them this could be a really great game! I like the pixel art style, the station being the Death Star gave me a good laugh.
Great job!
