A fun and incredibly charming game! I would love to see more levels of it. I notcied, however, that you don't actually need to write the codes to activate them? It seems that the buttons still work (even if you have no idea what that cheat code does). I really like the visuals and the music, it's so cute. But the implication are also kind of terryfying, which creates a very interesting atmosphere. The puzzles were fun and engaging, I especially struggled with the last one. Also the idea with the cheats altering the game is pretty fun, too. I think it would be even cooler if you had to find the cheats while playing, perhaps deecoding messages inside the game.
