I was planning on making a 2D game or tool to coincide with the Unity 2D Challenge and I wanted to try my hand at extending the functionality of the Isometric or Hexagonal tilemap from within Unity. Originally, I planned on just having hex tiles move in orthogonal fashion down the screen and wrapping my head around what it would take to transform or render different tiles in interesting ways on the grid. If anyone is interested I'd be more than happy to have you join into the fold here in the digital Midwest. We have an interesting bunch out here! I myself have been doing 3D stuff for a while but I am just a novice programmer at best!
and good luck!
