Voxatron is what came to mind for me given OP's requirements. I own it but still haven't used it myself, but given it's from the same group as pico-8, I would bet it fits the bill perfectly.
A few threads here recommend pico-8, however, you said he specifically wants the game to be 3D.
The developer of pico-8 has another project named Voxatron which is similarly accessible like pico-8, but for 3D gaming.
