I’d like to agree with what you said to some extent (sadly, even the monetary parts, but that’s just how a company is supposed to work I guess?) but complete radio silence for 2 months with this being the only follow-up is something that has definitely worried a lot of people. Sure the other 2 points I’ve made especially about “Pro” Sound Effects having audios of questionable quality is able to mitigated but the main point is that the lack of communication is definitely not up to standard from what I can see.
At this point, is having a follow-up so difficult for them now? Even if they don’t have to make changes immediately, even if they have to do everything carefully, about 2 sentences of re-assurance would definitely help a lot.
