Hello,
I started unity a few month ago and i need to make a lemming game.
But after a lot of research, i didn’t find anything working to dig in platform. So i’m asking for some help 
I want the character to dig on a wall or on the ground (horizontaly or verticaly) and detroy the platform where he is digging to do something like that :
thanks.
Many different ways to approach this. If you do a google search for “unity worms terrain”, you will find a wealth of information from other users who have accomplished this. If you want to just go for the real quick route, this is the first popular AssetStore entry that does what you are talking about: Unity Asset Store - The Best Assets for Game Making
In fact, the WebGL demo in that package has a similar art style.
Thanks for the answer,
i did some research and i found something that should work:
it’s in spanish but with a lot of pictures so it’s pretty easy to understand.
Actually worms is done by pixel perfect, basically “Old school tut coming up” what they had at the time is two image the image that you see and a masked image, the players where checked against this mask “2 colours infact Black/White”, they then edited this as well as the main image, several other games did this Worms springs to mind as well as super sprint I think.
