I really like the idea of the game, but I am torn about the time limit of the cheat codes, which also seems to be mandatory, as the combat is quite hard. Cheats are fun, because they are not part of the actual game, but by adding a time limit to them, they become a gameplay element and with that it might be better to add an additional UI for them (cheats currently used, cooldown). But it might be a better to embrace the chaos aspect of cheat codes and go wild with that.
