Every developer starting to milking and late nowadays!
One, Covid is affecting everyone, and that also means that these creators may be stuck in their houses and while you'd think that means they have nothing better to do than code their games understand that people need some kind of release-and they aren't getting it. Cool your jets, stressful time means developers are having a harder time getting these projects mobile because a lot of things are bearing down on them.
Two, Mythic Manor is one of a nice handful of games that can take a couple of months to develop because the scope of the game is harem based and thus takes time to give adequate updates to the core list of characters and as well provide extra spice in terms of side content. I f you do not like to wait there is plenty of stuff to choose from and if all your favorites are taking a while? See point one and go do something else with your time while you wait.
Lets all chill the fuck out and remember these developers are human beings and they have friends and families and other shit in their lives that don't revolve around these games at every turn. Update Drones, you'll know when an update happens when it fucking updates, for anyone else who wants to complain that they're milking it or taking forever, grow up.
