For review purposes during Scream Jam 2024, here are the codes you need to directly access levels 2-10:
Level 2: EJK
Level 3: WHU
Level 4: ZFQ
Level 5: ECY
Level 6: EET
Level 7: FJH
Level 8: HZO
Level 9: RYN
Level 10: GIL
Select option 3 from the game's main menu, then type one of the three letter codes.
If you complete level 10 starting from any level other than 1, you will get a congratulation message. Only those who have completed levels 1 through 10 in one session will get to see the true game completion screen!
