Today's update looks large, but is actually pretty minor. This update fixes a glitch that was preventing the "Grade A" achievement from triggering after scoring an A rank. If you successfully fulfilled the requirement previously, the achievement should pop automatically when starting the game.
I have also rebuilt the game using the newest Unity editor version in order to patch out a potential vulnerability within the Unity engine, as per their suggestion. (This is the reason for the large size of the update, so I apologize for that). Let me know if you notice any unusual side effects suddenly appearing with the game!
