Nice work under your time constraints!
I found the attachment system to be a bit finicky, with the most reliable approach being to plant them directly in the middle of the character, and I also didn't see how to rotate the attachments.
I recommend resizing your scroll boxes, as they currently extend pretty far past the content. I'm not sure if the music fit the overall vibe, and I thought it would benefit from some more in-game sounds.
I enjoyed rolling my guy around while rockets fired off randomly!
