It would be a shame if this great game were abandoned. "The bud was cut before the flower bloomed..."
In all seriousness, this game is not abandoned and this creator is one that actually completes all his games, albeit sometimes hastily.
Your avatar says New Member (and I'm quite new myself) but I'll share two things I've found about F95zone since I've joined that really helps me judge the progress of games.
The first, this site is really good about giving game threads a yellow "abandoned" tag after a certain period of time without news or updates from the creator, so the absence of a yellow tag is usually (but not always) a good sign that the game is still ongoing.
The second, there's usually a link on the first page to any open forums the developer uses to communicate about his or her game, e.g. patreon, itchio, pivix, the developer website, etc. Even if the posts are behind a paywall, you can pretty much always see the dates / frequency of the developers posts to know he's working on it.
In the case specifically, the developer is working on two games concurrently and he just put out a release for the other and his website says this game is the next to update.
Sorry, but it seems I'm always long-winded. I hope that this helps -not just with this game- but determining the status of any game you're following. Have a wonderful day.
