They do, but the team has literally taken over six years to produce a single (very buggy) level. There's a certain degree of patience required on the consumer's part, but even single-person teams should be able to produce more than that in that time frame. It's no longer "quaint," and it's perfectly valid to criticize (or at the very least be disappointed) the developer's for having sloppy organization.
And, just to point out, that single level they produced was in much the same state as it is now (sans boss) six years ago. The only thing they've been doing this entire time is reworking that level over and over and over.
They are a team of only 2 people, one doing the art and the other doing the programming, and one of them is doing the writing but I don't remember which one or if both are. Over the time they have been working on the game, they had to do the artwork, the coding, level design, bug fixing, writing, handling their own advertising of the game, patreon and subscribestar posts, manage the itch.io page and any other places they upload the game, all while early on trying to learn a game engine and now doing so again since switching to Godot but with an easier time.
They have admitted to having sloppy organization at the start, but they seem to have gotten their heads on straight and are actually getting somewhere. The devs also probably have jobs other than working on this game, which if they do means those jobs will eat into the time they can work on the game, not to mention other facets of living they likely have to deal with. They're not a company, they're indie devs making a furry platformer game with porn in it.
