So I had my game working and had my level 1 working thoroughly. I now needed to make more of my level. So I decided to make 2 more levels. When developing these level I needed a way for them to differentiate between each other and I needed each level to oppose a new challenge for the player. So for level 1, I decided to get rid of the Side angle platform and have that introduced in level 2. So the player can use them to boost himself up. For Level 3 I decided to introduce moving platforms. This will make it more tricky for the player to land on. I also introduced vertical patrolling enemies and a trap.  These changes allowed each level to have a new challenge for the player and keep the player engaged.
