You got a decent thing going here. I'm a huge fan of pixel art with 3D art style, so keep doing it! It needs some polish, as sometimes you could see through the floor or sometimes my golems would just explode everywhere? A more proper tutorial is already mentioned by other comments so I'm sure you're aware. There's a lot of polish to be done, but I think this could be a fun little roguelite with some enemy and golem variety!
