After we decided to use terrains rather than planes for our project, I added the terrain into our scene and raised some parts up to represent the hills and mountains. Because the players are not interacting with the trees (they are just there to be aesthetically pleasing), I plants trees on top of the terrain rather than have them as separate gameobjects so our hierarchy does not look too messy. The placement of the enemies and herbs was also changed since we decided to change the position of the houses to make them looks more compacted together. With this, the player can take a short amount of time to explore the entire map. With the changes I made, the entire village will be bordered by a forest that is bordered by mountains and hills. The "end of the map" the player will see is the mountains which he/she cannot cross over.
