Not sure what's up with that other commenter... anyway, really cool work for the jam! I think it's super impressive how readable the environments and objects are for such a small resolution. Looking around in real 3D space in one of this nokia games is surreal.
Thank you! Yes, I'm really pleased with how the shader came out and I'm definitely using it in future projects, granted with a higher resolution. If you haven't already seen, I've uploaded a high res version that is linked in the desc. if you're at all interesting in seeing that :)
(And thank you for the sensical response, as apposed to some other people :p)
