Remember this author's name, and if you see one of their games pop up, consider it already abandoned. I always hit the watch button, wait, and see them abandoned, they're not worth downloading until you know for sure they're not being abandoned, because then you'll see the concept and if you like it it'll suck when it gets abandoned.
If the athor ever finishes a game or at least put enough content in it that it can be called a decent game even if it's abandoned at around the end or the middle point, it could at least be worth trying.
