This was really fun to play, I like your take on the theme where the player gets to make their own boss and fight it! I really liked the intro cutscenes at the beginning, it really set up the story even though it was just a simple plot of an engineer trying to make a killer machine in 5 days. I would love to see an expanded version of this, where maybe you could save up the scraps to attach something even stronger... But overall, really cool! Good job!
