Bang! Bang! (Cannon game from 1990)

I'd like to see a Challenge with the classic windows 3.1 game Bang! Bang! as the goal. I know that the velocity, wind and angle stuff isn't a challenge for you, but I'm very curious about the random ground and the fact that the projectiles actually **modify the terrain**.

I'd rather watch it being done with processing, but I guess it makes more sense to use p5js for this project since it's a 2 player game.
