I see. Using "just the toys in the toybox" is the definition of this particular jam. So, yeah, having a toy drive before the jam probably makes more sense. Well, if you keep the easy mode for next year, maybe you can do it both ways.
Anyway, thanks for hosting the jam. It actually got me to make a game after a very many year hiatus. I had a whole lot of fun. I got the idea for my game shortly before downloading the start carts and was on pins and needles hoping I could actually make it fit with the assets. Probably the wrong way to go about things. (What's new!) The idea for using the railroad tracks came straight from the toys in the toybox, though, and it made for a way better game than I first envisioned.
