Oh, thats a bummer! I dont know why devs dont puts their focus on one game at a time.
There is a very good reason for that. Many devs become bored with projects and abandon them in favour of their latest and greatest ideas, sometimes those ideas are better than the current project, sometimes worse, it doesn't matter that much for this example, however once a project is abandoned the damage to the devs rep is done.
So it's easy, stick to a project and your fine, right, well equally as many devs drop out of love with their own projects, things get rough, they take flack for problems with the game, perhaps an update is late, perhaps there is some portion of the content or the story direction that the fans dislike, even if it's a minor thing and won't be a big deal the end it can demoralise a dev and if that dev is not sufficiently confident/invested in/in love with thier game then they could well burn out, decide dev work isn't for them and disappear from our radar entirely.
What i'm getting at is that if what it takes to keep a dev engaged and productive is to have a project ongoing that is very much a B line project to drop errant ideas into or to try things out in then i'm fine with that. While i do understand the frustration of looking to see if a long time Dev like Baal has got an update out for superpowered and instead find that we've got 0.3 of "the loser" which is little more than an interesting tech demo i do realise that working on a single idea for over a year is also frustrating for the dev, simply put for many there isn't enough time to make all the ideas into full fledged games, better to purge the small ideas with games like "weird shit" than to let the new ideas effect BM, be it content creep, distraction or w/e else.
It's not an ideal situation to have a dev working multiple games at a time IMO but it can be the best compromise for the longevity of both the dev and their projects.
