Thank you for your reply!
*Won't eat lemons: Currently they will eat lemon only when they're hungry rather than thirsty. That's a bug to fix.
*Items only show on UI: Most facilities can store some items, that's why sometimes you don't find items on the floor.That's not a very clear design. We'll improve it by maybe show facilities' storage on tooltips.
* Sharks: Many people complained about sharks. Currently, you build more raft on the first floor, there'll be more sharks, which I think, is a bit unrealistic and misleading. We'll cut down the amount first. And figure out a more realistic pattern, like lured by food or corpse. But that'll probably be a single update for creature behavior.
*How to get bones: Currently, you can only get bones on a dead body. We'll add more approaches. Actually, bows and arrows are useless in this version. We'll add weapon system in the next update( in 2 weeks).
*Can't set meat rack: Press R to rotate blueprint. Like hammock, this guy can only be built if facing the correct direction. We'll add a red effect when you can't set the blueprint, rather than showing nothing.
*Mute: Press M
And thanks for other bugs, we've recorded. And if you would like to keep giving us feedbacks, posting bugs/suggestions/question separately on the sticky post would help us get organized.
