He's not abandoning the game. You can find out more by reading the dev logs people have posted.
The dev has not given any clear indication that the game will be abandoned. Had a bit of a panic about remaking the game to change various not-safe-for-credit-card-companies themes in the game, though it seems the dev has calmed down from that. Comments are more just people reading the writing on the wall, the development of this game has slowed down to a crawl, the dev has dragged out updates being near release for months, and at one point last year even just admitted he was lying about working on the update when he had actually taken a break. This game isn't going to survive updates taking this long, it's most likely going to be abandoned at the rate things are going.
