Relatively decent quality when you looked at the jam's submissions back then :).
I remember my game's (Package) source code, it was absolutely horrible. When tasked with how detecting individual boxes' collision with each other, I resorted to MANUALLY detecting them (e.g. if box1 colliding with box2, box1 colliding with box3, etc.).
It was a pain - and to this day I laugh at the fact I could've just used 2 for loops to do that. But it was my first game and I'm proud of it. You should be proud of this game too - don't call it low quality :)
