I like the ingenious idea of repurposing an unfinished jam game into a commentary. The game becomes a sort of living document about the creative process. I agree that the visual trick of coding a moving train is really enticing and has great potential for a setting in a fleshed-out project. You have a great commentary voice and it really delivered on an experience of seeing someone talk through something they had created with pride. It's surprisingly heartwarming. Hope you're able to finish it post-jam!
