Minigame Select, Stage Select, and Progression Check Coding

These 3 should be coded in tandem as they are closely related to each other. Health 101 and Dealing Damage are restricted until Basic Movement is completed. Medium and Hard are restricted until Easy is completed. Refer to Player Progression state chart diagram.

Oops, my first implementation simply locks each level until the previous level is completed. I'll update it to reflect the behavior outline above/in the Player Progression state chart diagram before we clear this issue.
