I'm thinking if I do try for a kickstart, I won't do it until after I get to the point I make my post on Minecraft / Terraria's Other Games forum. If feedback is strong, I will go for it. Otherwise, I won't.
On another note:
BUGFIX: If you swung a weapon, say pickaxe, but swapped to a different item mid-swing that didn't have a swing animation, the next time you swapped back to the pickaxe it would pick up the swing where it left off. This often led to unintentional block damage. Fixed.
BUGFIX: This one is tied to the above. If you swung a weapon, say pickaxe, but swapped to a different item mid-swing that did have a swing animation, the animation would continue playing but would swap to the new weapon. So you would swing a pickaxe, swap to a sword, and it would be as if the pickaxe changed to the sword mid-swing. Fixed.
ADDITION: Tile damage has been in for a bit but any tile you hit would take damage if was able to do so. If you missed and hit the wrong tile it would take damage and stay damaged until you either destroyed it, quit/save+quit/reload. This was especially frustrating with the above bugs, as you could accidentally damage your home. Now, tile damage resets on the last tile hit if the new tile hit is a different mine-able tile. Essentially, only one tile stays damaged at a time. Whack a new tile, the old tile gets restored.
These fixes, and the last addition, surprisingly give way to chopping down trees as a single tree, and not individual blocks. The damage a tree needs to take before it is felled will be a function based on the hardiness of the wood (how many hitpoints each block has) in relation to the height of the tree. Surpass the damage needed, the tree de-spawns, and the game will spawn a number of wood relative to the tree's height.
