I cannot f* believe he has so few supporters :|
There's plenty of crap with a lot of patrons, and this (potential) gem has little to nothing..
This is still in the first week or two of the first release of a first game by an unknown developer, so it's really not that surprising. Has the dev even been pushing the game at all, or just relying on the community's word of mouth and being on Patreon as the sole forms of promotion? If so, it will take a while to pick up steam, probably after they have a few good solid updates at regular intervals.
On a semi-related note, if they aren't careful and replace their banner soon, they may end up losing months of funding when Patreon puts them on review and makes them wait ages to get back to them after they finally clean up their page to remove the nudity. I didn't bother to check the screenshot they have a link to on that page, but if that leads to another nude (or possibly the same in the banner), then that'll be a strike against them too. Right now they are flying under the radar, since they aren't getting many views/patrons yet, but it's only a matter of time before they find themselves in Sauron's fiery (and irrationally puritanical) gaze.
