...Feature Creep?
Anyway, no, I think I'll do a mix of RDD and typical NES code entry. In the in-game options menu, there will be a cheat list section. The cheats can be enabled in that menu by entering them at the title screen/title screen cheats menu. Once unlocked, they can be turned on or off in-game. Once the game is exited, however, they leave that menu and have to be re-entered at the title again. This might annoy some people, but one of the biggest things about childhood gaming for me was having to write down your cheats/maps/secrets and hoard them like some sort of treasure. I loved that experience, and I think an homage to it will be appreciated.
Yes, that font is the typeface used in Lovecraft's Diary. I'll use an actual font for it in game overs/titles/conversations with Old Ones or whatnot/etc.
