I think it will be cool if the ground collapses when you dig under the building. (The pile of rubbles later disappear) I'd love to see what the mayor and the cowboy have to say about that.
I coded the wall jump for my game and it was pretty hard(for me). I find the way you implement the wall jump to be interesting.
That's a neat idea, voluntary destroying the town by digging underneath would be a fun Idea to play around with haha, and thanks for checking out the game. The wall jump mechanic is fairly simple, if not a little rushed - I just put the player into a "wall slide state" if there is a wall to left or right of the player (but not below them), and if the player jumps in this state they are given some horizontal speed added to them
