There's a bit too many mechanics involved in this, which feels like it's there for the sake of being there. A general principle of design is a "Why? What? How?" question (Why are we designing this? What does this do? How will this be made?) and it seems like you focused on the 2 latter rather than the first "Why?". The elemental mechanics wasn't adding anything (in its current form, it can add depth layers in combination with others). But since I could place things on each row only for a short amount and that was limited, those mechanics were confusing more than helping.
Otherwise, good artwork, and definitely a good attempt! Just wish it tried to find the fun with a smaller core before layering on mechanics (I have been guilty of this many times myself), but you'll learn that anyway with successive game jams!
