When Nero Caesar received a critique from one of his political opponents, the critique included the accusation that Nero was a poor lute player. Nero responded by saying he was god's gift to the lute, and that if his opponents were willing to misrepresent Nero's skill with the lute, they were willing to lie about everything else and all criticisms directed against him were thus invalid. In spite of this clever deflection, hundreds of years later, "While Rome burned, Nero played the fiddle," continues to be a popular saying.Starting a critique with "how embarrassing" or "as far as I know" makes you look pretty inflammatory and uninformed and deflates the points you made currently and previously. Keep in mind that a critique only has as much value as the reader(s) of the critique derive(s) from it.
If there's a valid argument for why Calamity needs the Abyss, Planetoids, the Calamity biome, the Undertale references, the Drunken Princess, the "lore", and so much other chaff, I haven't read it yet. If this makes me ignorant, so says you. However, I would take some caution regarding the amount of blind praise you're getting here and likely in your Discord where you're able to exert more control over the dialogue. While criticism should always be taken with salt and the knowledge of your project that an outsider can't possess, the same is equally if not more true of adulation.
