Hard to tell. You have said it's buggy, but it's just too bad. Of course, Scratch isn't meant for serious project, but the fact you're lazy doesn't justify the flaws of the project.
The idea is quite interesting, though the way how the project is linked to the jam theme is not very unique (I don't consider my own great as well tbh). Learn some engine - I'm sure you can succeed if you were ready to go through Scratch's hell to take part in the jam.
