I love entering these game jams and have used tools like, libgdx, pygame and java from scratch to make simple 2d games. I've been thinking of trying out Unity for a while now. Do you think it's a good idea to use it for this LD without any prior Unity experience?

I don't mind ending up with a shitty looking game, I'm used to that (see image below) :p But I do want to be able to publish something in the end.
