Jesus man, the dev literally makes full stories in batches, they released Rahi's story, Tavi's route and the newest Rynard's route in a span of few months. Both completable stories also with bugfixes etc. that most games these days would take years to do one of those. And on top of the last one, they included a highly popular mod into the base game for future mechanics and activities. This way the game development can progress way faster than normal and it also supports the mod creator to continue and not abandon it (while also allowing the dev to work on it on their own if necessary). Why do you play-test a game that's v0.1 if you expect stuff to be complete? There are v0.8+ games that also have unfinished mechanics, yet you complain about a frikking 0.1 having a mechanic that's working well (the fact that it is a working mechanic and not just a skin or overhaul should give you the idea that it's more expanding and a wonder that it works this well), just not expanded enough yet, and you treat it like it was breaking the game when it just doesn't have everything you want from it yet. Like literally, get your head out of the gutter, your whole feed is full of you just trash talking every game here. This dev keeps coming with updates all the time, updates that finish all the stuff that's added. One of the few devs that actually cares and tries hard to improve the game and it's mechanics, and you trash talk it like it's offending you ffs.
Come back when the game is in later stages of development.
