I don't know what your plan was for the full game, but I think you could leave it as a sandbox just adding a few more materials and the option to cut what's already been glued. That would already make it a cute digital toy to play around with.

It was meant to be very sandbox-y, mostly just ran out of time to add any sort of UI and options, cutting what's already been glued is something I really wanted but also completely broke everything so I ended up only adding features that didn't bug out. I do want to rework the code and make it more playable though!
