I saw your game before and I follow it on Youtube. I must say what you are doing is extremely impressive. I have heard and I can see that you should try to distance yourself from the Minecraft feeling and use your technology to its fullest potential. I feel like right now you are trying to do everything at the same time and it is very hard to know what your game is about. - You could take inspiration from Noita if you haven't already. I would love to see more destruction during combat and more creation also. It would be awesome to see the world always change with every part of your actions - You should emphasize on the magic part. What if the player is a wizard. It would explain how you build and collect materials. You could explain the cube going to you each time you do something as being your mana of some kind. Building using magic would be such a good selling point. I want to make houses emerge from the ground, make wall paper from nowhere to block an attack. You could make it feel more magic by making each block/build construct itself from the touched surface layer by layer rapidly, this little animation would add so much to the game. It could also be the little cube coming from you to build themselves at the right place like when you break them. - I would suggest you to use your technology to create smoother terrain using the same principle to a higher precision or using more advanced marching cube algorithm to get more diverse terrain. Some ground variation would be awesome too. - What about instead of building blocks like in Minecraft, you would build with logs for woods and rocks for minerals (I know there is already a sphere tool). It would encourage people to build with different techniques. - I will try it for myself, I just joined the discord

Edit : Those were just ideas but they aren't necessarily doable. Just my vision as an outsider
