As you've said this is more of starting point, but its a great start! Read what you have planned, followed you and will check back later on your progress! The graphics are great and I was really charmed by the stump actually falling when I dug around it. I dug around the house hoping it would fall too but nah. You've probably already thought of this but if you aren't going to give the house physics you should probably put unbreakable blocks under it or something. I dug so much that I never could have gotten back if it was enterable.
As far as my prefence goes, I would like if I could hold the chop button to break blocks rather than mashing it. Dunno if it thats better for the game feel or not, just something I would prefer.
Good work!
