Optimised how levels were drawn by combining the four separate level functions into one (which was put into its own file). This would also prevent exponential scaling in the future seeing how with 4 new game mechanics would result in 64 level functions, creating thousands of unnecessary lines. Furthermore, AI was used to generate a quintic easing function for the mountain lerps, allowing for smoother transitions. In the process, a camera focus bug was also fixed.

note: the to-do list is removed since from this point onwards solely new features will be added.
