You said it yourself, cheats are nothing of value and low effort, and they're not relevant to the game's content. And this is exactly WHY they are the rewards for high tiers. Or would you rather suggest locking real content behind high money tiers or not giving anything to high money tiers?
Also, if it was not for these tiers they would not even be in the game in the first place, for example, the Steam version will not have them.
I don't want to name them because I don't want to badmouth fellow creators but I know of many Patreons where cheats go up to 200+ euro, and we at least limited it to 100 euro. Also, others even limit the amount of height tier cheat rewards that can be bought, to give a feeling of having to grab them before they are gone. We would never do this for something like cheats. But only for things which require extra personal work from us, since we have limited time to fulfill such rewards.
But I will try hearing you out, no rewards are not an option, and if simple cheats do not work, what would you suggest as a reward instead?
