How do I create a diggable floor?

Hi, I'm very new to construct 3 so bear with me, please. I'm creating a game for a class I'm in and I want to make a game where the player can dig/mine the ground in order to find treasure. this would be a 2D platformer tyoe game. I want something that can be seen in Steamworld Dig!

Look about tilemap.

You can use a tilemap to display the ground (like a tileset of the ground everywhere) and then you are digging by erasing each cube of the diggable ground when they are overlapping with the shovel, for example.

What to look for at least:

Tilemap.

Object overlapping with another.

Overlapping based on collision on origin from the sprite editor.

Removing objects (sprites) is probably the easiest way but it can cause lags and slowdowns on a larger map. I don't know if this guide would be of any use? - construct.net/en/forum/construct-3/how-do-i-8/player-dig-166671
