Game:
- Revamped Cheatsheet UI

- Replace Time with Stats on Solutions
- Added 9 puzzles
- T-Flag is now a read-only Register
- Area and Cycle stats shown on Success
    - Area: Number of different Memory Addresses or Registers written to
    - Cycles: Each step, the max cost instruction between the 4 cores is added to the total. This is due to the synchronisation being round-robin/lockstep.
