going full circle, are we.
you made a 2d volume-pixel game by name. and now want to make it 3d.
making your 2d minecraft clone into a 3d game, makes your game a regular minecraft clone.
is this a good idea? depends. if you included stuff to make it fun in 2d, will those things work in 3d? my guess is, that some people like your game because it is not another 3d clone of minecraft.
thanks. good luck with your conversion back into the third dimension.
i suggest you have a look at this https://www.luanti.org first, so you do not reinvent the wheel. they do have an actual voxel engine. i believe your game should have something they do not have. might be something simple, like being a simpler game or a mechanic. but in direct competition, there are many minecraft-like games.
