If it makes you feel any more comfortable their only other game was completed and is highly rated and praised on here. You can even download the full version of it free on here.
I know dude, I have the patreon version of the gemstone of a visual novel once in a lifetime[OIALT] and saying that its a great one would be an understatement. But dude recently 4 of the games I backed got abandoned and it stings. That's why I haven't downloaded this game yet, because I bet you know how amazing Caribdis games are and I seriously wont be able to take it if something happens midways because how invested I will become in it if its anywhere near as good as oialt is. And anyways I can always get the game after its finished right? :D
