SpriteStack Voxel Editor
In the featured art, I don't see the why of the voxel sprites compared to the beautiful 3D rendering.I probably love my old classic games more than average. (Still have Prince of Persia 1989 installed.) And love some new indie game with old graphics. (FTL is awesome if you haven't tried it yet.) But 3D and proper physics enable so much more. It feels odd that so much time is spend on recreating old game feeling for some nostalgia sake compared to let's say exploring new 3D physics engine. (Teardown is an indie awesome game if you want to play with an adventurous physics engine in 3D.)
