This is actually my first LD48, and I doubt I’m gonna finish with any reasonable level of polish. I got off to a late start here- only been working on this for a few hours. Anyways, here’s a screenshot of my WIP (please excuse the programmer art).  The hero approaches the sage and pops a pictographic speech bubble showing the item he needs. You must then arrange blocks to build that item, pixel by pixel, so that it matches the required item icon. Simple stuff, but quite puzzling in practice given the rules I’ve got planned for block placement.
