Sneak Peek to the next level + Development Notice
Hello everyone! I would like to talk with you all about the future of the game.It's been some time since the game released already, and i am so happy for all the support! So i am happy to share some information about what i am working on, what i will do for the game and everything. First thing to say: The first of many new levels being added to the major update is: Poolrooms. Here is a screenshot of how it is right now!Stay tuned because i will keep posting new about all the new levels that are being developed. (be prepared for the original levels!) Now answering some questions about the future of the game:Q: Are you going to keep updating the game?Yes, absolutely. Some might've noticed, i took a break from deploying micro-patches fixing bugs and levels balance some time after the release. The reason for that is that i am 100% focused on the MAJOR UPDATE, which is the next update for the game, coming in a few months.Q: What can i expect on the Major Update?I wouldn't call it a Major Update if it was only new levels. I am doing a rework to a lot of things that are in the game right now, since now i understand what the average player expects for the game, now i can truly make the experience everything you would like to see. On the major update, i will add new player mechanics, exclusive (original) levels (and be prepared for these btw), rework/adjustment to every single level on the game, aiming to make it less frustrating to play and more pleasant. Furthermore, i am looking for completely unique entities, new amazing items, satisfying and cool puzzles, and making the game even more optimized for mid and lower end PCs.Q: What are the new levels coming on the next Major Update?Keep an eye on 👀-sneak-peeks channel on discord. I will continue to post screenshots/footages of the new content i am currently adding on the game. For now, i won't spoil every single level, so you can try to guess them out Q: Is it possible to get early access on the Major Update and playtest i...Read full article on Community Announcements (lz)AnnouncementsOfficial
INGAME VOICE OVERHAUL + HUGE QOL CHANGES
GAMEA lot of code improvements.Fixed some of the new texts not translating on some languages.VOICE CHAT OVERHAULThe In-Game Voice Chat has been completely changed. It offers a much better voice quality, more stable connection to voice (so voices wont cut/have weird effects anymore) and now the voices are realistic (the voice sounds muffled when hearing another player behind a wall now!)Now the options of increasing your own microphone volume and increasing the volume of the other player's voices correctly work.Finally you can change your Microphone Device more consistently and don't need to keep resetting it forever.Changed the ''Talking'' UI Feedback on the corner of the screen when the microphone is active ingame.DEATHNow the dead player drops all the items on the ground before dying. No more wasted almond waters i guess...INTERACTION HELPERNow, when aiming on a interactable object, it shows a text on your screen: Press \ To Interact. This should help new players to understand the mechanics.LEVEL FUN (how many times have i nerfed this level already?!)ALL MINIGAMESIn case you didnt noticed/see, now all the dead players revives upon minigame completion, NORMAL DIFFICULTY ONLYPRESENTS MINIGAMEReduced slightly the speed of Partygoers when spotting you, so now you have even more opportunities to hide under a table or find a safe spot.Fixed the rare bug where Partygoers could KILL YOU VIA BLUETOOTH?!! (i dont even know how this happened... i hope it is fixed...)BALLOONS AND TABLES MINIGAMENow the timer to pop the balloon changes the color depending on the time left!Timer >= 40 seconds? -> White Color Timer Yellow Color Timer Red ColorRead full article on Community Announcements (lz)Patch NotesOfficial

Hotfix v1.0.2 (Adjustments to Level FUN)
GAME Now you can rebind the keys to open the chat (Thank you @Peti) LEVEL 0 Made some extra almond waters spawn on the level Bacteria Lowered the volume of the Bacteria by ~5% (should already feel better and not explode your ears i think) LEVEL FUN Presents Minigame Made the tables on the Presents minigame more consistent and efficient Jumping Minigame Made the jumping minigame significantly easier Balloons and Tables Minigame Increased the timer on the ''balloons and tables'' minigame by 10 seconds on normal difficulty (1m30 -> 1m40)Read full article on Community Announcements (lz)Patch NotesOfficial
BIG HOTFIX (v1.0.1)
EARLY ACESS HOTFIX v1.0.1GAMESANITYNerfed the Sanity Drain Rate (increased the time to die from sanity) in ALL Difficulties: Normal: 16.6 minutes -> 20 minutes Hard: 13.3 minutes -> 16 minutes Hardcore: 10 minutes -> 13.3 minutes SPRINTINGAdjusted player sprint mechanic: Now you don't need to reset the sprint after getting the sprint canceled (canceled by out of stamina, walking backwards, or standing still) What this change?You can start sprinting right after moving, if you were standing stillYou dont need to press shift again after having the sprint canceledThis means you now don't need a ''impulse'' by walking forward to be able to sprint. This will help specifically on the jumpy minigame on level FUN, but overall a quality of life to every single level.LEVEL FUNPRESENTS MINIGAME ADJUSTMENT:Now you can hide under a lot of different tables on this minigame, just like the Organs minigame. So now you have a extra chance to not die :)BALLOONS AND TABLES MINIGAME ADJUSTMENT:Now the minigame start automatically after 10 seconds, instead of activating after interacting with the note. Thank you so much for all the reviews! It makes me so happy 🧡🧡Read full article on Community Announcements (lz)
