I played a dozen of runs with cheats. I advanced further with them, seeing new levels and enemies. I rescued 3 npcs, and unlocked a handful of new weapons and items. I even got slightly better at the game after a while, being hit less. But my skills were still pretty far away from actually beating the game, even with 4 extra hearts.
In the end, even with new weapons and more health, I dropped the game. I just don’t like the combat that much.
