Bud the developer is active in their discord updating the community what is happening just have a look in the minor announcements section.
Just from a few weeks ago they explained that they have had family health issues but let's not let that get in the way of your fapping bud...
Also almost 3 years since the last update? Pretty there was a Halloween update so that's 5 months not 3 years.
Remember something bud this is one person developing a game that has more features than pretty much any other in this type of category, that's has some of the smoothest animations and gameplay for anything of this type that isn't just a basic renpy or unity build.
But to summarise good things come to those that wait.
Overall I give your crying a solid 1.29/5 as if you bothered to just check the discord or ask the dev in discord first before your little hissy fit you would have known what is going on.
