This Abandoned tag shouldn't come as a surprise to anyone, just look at a developer's previous work to see a distinctive pattern.
Some devs get bored or frustrated with their projects and just drop them like a bad habit.
Others will do a speed run in the last update, forcing a closure that wasn't nearly built on.
There are some novels and games that I am sad to see go, this is one of that I will lose a second of sleep on.
