I did find this project easier to create than the space invaders game, though this could be due to the fact that Unity didn’t randomly break on me during the making of this game. I did however run into a small issue, of my character drifting through objects. I later realised this was due to a script not being attached, and my character was then unable to walk through the objects. I did try to pick a grass colour for the background of my game, however blue and green are the same colour for me and I have been informed I did in fact pick blue for my background colour. My zombie character (the enemy) respawns randomly across the map after being destroyed. I also added boundaries to this game to avoid the character being able to drift off screen. I discovered when the character goes off screen its very hard to get it back on screen, which is why I implemented a boundary for both the player and the enemy.
