Hey! Thanks for the suggestion! A blacklist had crossed my mind much earlier in developing the game, but I guess I kind of lost the plot adding in so many features. It wouldn't be too hard to add, so I'll definitely keep it in mind!
Although, I have been super busy lately, so I apologize for the late reply. I haven't gotten much work done on the game recently, but my schedule should clear up in the coming weeks (or months, idk)
