It's always nice to see someone take on the extra challenge to build 3D games. After I got past figuring out the interaction basics I had a good time with it. Crafting mechanics are pretty solid and are actually quite fun. Given the fact that you went for 3D instead of 2D, I'd say graphics were pretty good too. Everything made sense and was easily identifiable.
Not bad for a first 3D game, specially due to the time constraints. Nice job.
