Once I figured out how to play, I found a lot of functioning systems that seemed to have quite a bit of depth to them. I'm super unfamiliar with the Minecraft genre space, so it's hard for me to evaluate this game in that context. But I liked the loop of working on upgrading your items so you could dig and harvest faster. Eventually I dug myself way down into the earth, and was amused to see how things changed as you go down.
I like the way the water rearranges when you clear out the space underneath it.
Not sure if it's possible to make the window resizable. It was very tiny on a 4k.
I thought I softlocked myself because I placed a piece of sand on myself when clicking to try to use my ship, and got stuck. Then it took me a long time to figure out how to open my inventory to do crafting. Should definitely put that on the itch.io description page alongside the other controls.
Good job making this. :-)
