The Shape Sorter is a really important mechanic/system I need in this prototype. I want it to be a fully-rotational 3D object the player holds in their hand. Instead of the typical rectangular shape, maybe something cooler, like a cylinder that encourages looking at it from different angles. On slots where newly acquired shapes can be fitted (as soon as they’re found), stars fizzle and pop within the slot to draw attention. Since it will be 3D and rotational in hand, this will be more engaging and fun!
