As a bad artist I experimented with a lot of "low skill" art styles: minimalism, simple vectorial art, neon, moebius/sable inspired style (cellshading+outlines) and more recently 3D pixel art.
I was drawing inspiration from the 3D dungeon crawlers of the mide 90's. But as I have limited pixel art skill and as I didn't had a lot of time, I used a very low resolution (16*16).
So, yes, it kinda look like minecraft but with billboards.
