Block Destruction Indicator

There are currently no visual or audio indicators in the game that tell the player if a block is being mined with the correct tool. For example, someone could try mining Ancient Debris with an iron pickaxe and lose that block forever (as they used an incompatible tool), and not know why the block was destroyed. For casual players or a younger audience, this kind of experience could repeat itself numerous times throughout a playthrough and could be a source of unnecessary frustration. I suggest a visual marker to highlight whether a block will be mined or destroyed. One way would be to alter the cracking animation (for example, make it a different colour for destructable blocks), or to include a unique sound for destructable blocks. These indicators would be subtle but could help make the game more accessible to all players without altering the experience for more dedicated players. This feature would also be especially useful for people with visual impairments, allowing them to mine and build with more confidence thanks to accurate feedback from the game.
