I spent yesterday making a grid system where you could move and setting up a basic graphics pipeline etc., then started the jam "officially" this morning - I think/hope that's alright? Otherwise I'll just submit it on Saturday day next week I guess.
Making decent progress but err what with 3D graphics and all I don't have much mechanics implemented yet, but it's going to be pretty simple and puzzley so I think I'll be alright:
