World of Slime Troubleshooting and Known Issues
The bugs demo players actually hit — overblown audio, controller cursor conflicts, frozen input, fishing failures — with the workarounds that currently help.
The World of Slime demo is a pre-launch build and it behaves like one. Most reported problems are annoyances rather than crashes, but several will eat an evening if you do not know the workaround. This page collects what demo players are hitting as of late August 2026, separated clearly into confirmed player reports and things this wiki cannot verify. When TEAM42 publishes dated patch notes, the fixed items move to the updates hub and come off this list.
Audio Is Far Too Loud
The single most consistent technical complaint is volume calibration. Players report that the demo at low master volume is still louder than other games at full, and that the output garbles or crackles even through external audio hardware. If the game blows out your headphones on launch, that is not your setup.
The workaround is to set the in-game master volume very low — single digits, not a normal-looking number — before adjusting anything else, and to use your operating system’s per-application mixer as a second stage rather than pushing the in-game slider back up. Steam’s per-title volume control also works. This is a calibration issue rather than a hardware conflict, so nothing on your end needs replacing.
Controller and DualSense Quirks
The demo has native DualSense support on PC, and Steam lists full controller support for the game, but the implementation has rough edges. The most reported problem is a hidden mouse cursor competing with your stick and d-pad: the square button triggers a pointer, and even when that pointer is invisible it can remain hovered over a menu entry, so pressing confirm selects whatever the cursor was on instead of what you highlighted.
The practical workaround is to pick one input method per menu session. If you are navigating with the d-pad, avoid the touch-pointer button entirely; if you have already triggered the cursor, move it deliberately to your intended option rather than trying to switch back to stick navigation mid-menu. On the title screen you may need the pointer button to enter the main menu at all. Our controls page documents the current bindings.
Frozen Input and Menu Lockups
Some players report a hard input lock after opening a pop-up on what turned out to be another player rather than an NPC — keyboard, mouse, and controller all stop responding and the client needs closing. This is intermittent and there is no known reliable trigger to avoid, but two habits reduce exposure: approach NPCs from a clear angle so you are not overlapping another player’s nameplate, and close interaction windows before moving.
If you are locked, alt-tabbing out and back sometimes restores input; if not, closing the game is the only option. Progress in the demo is server-side for the most part, so you lose the current interaction rather than your session.
Fishing Not Working
Fishing failures come up repeatedly, and Mac players in particular report the minigame simply not functioning. Because fishing is one of the three ways to obtain slimes, this can stall a species hunt entirely. Before assuming a bug, confirm you have completed the quest that teaches fishing and that you are at a valid fishing spot — the demo does a poor job of signposting both, and several “broken fishing” reports turn out to be missing instruction.
If you have the ability and the spot and it still does nothing, you are likely hitting the reported issue rather than doing something wrong. There is no player-side fix. Report it and use field capture and synthesis for species progress in the meantime.
Synthesis Options All Greyed Out
This is the most common “is it broken?” report and it is usually not a bug. Synthesis requires specific inputs, and the interface does not tell you which ingredient is missing or what level is required, so a full material list can appear entirely unavailable. The bonded slime quest catches the most people. Check that you have the required species rather than the required count, and free up storage before experimenting, since a full box limits what you can hold to test with.
Missing Multiplayer and Empty Chat
Players regularly ask whether the MMO features are broken because they see nobody and the chat stays quiet. The early village functions as an extended tutorial, and population is genuinely thin in a demo, so an empty world is expected rather than faulty. Party play, 1v1 and 3v3 PvP exist; see how to play with friends for grouping. Note that kill-quest credit currently goes to the last hit, which makes co-op questing less useful than it looks.
Linux and Steam Deck
At least one player reports the demo running on Linux with no compatibility tweaks required. No Deck Verified badge has been published, and the demo is officially a Windows PC build, so treat Linux play as community-reported rather than supported. Mac is not covered by the demo at all; macOS requirements are listed for the full game, which our system requirements page details.
How to Report a Bug
TEAM42 has said the demo exists to collect feedback ahead of the December 2026 launch, and the official Discord is where reports are actually being gathered — several reviewers note submitting feedback there. The Steam discussion hub also works. Include your operating system, input device, and what you were doing, since the most valuable reports for the audio and controller issues are the boring specific ones. Our community page lists the official channels.
Frequently Asked Questions
Quick answers to the most common questions about the game.
Why is World of Slime so loud?
Volume calibration in the demo is far higher than typical. Set the in-game master volume into single digits and use your OS or Steam per-application mixer instead of raising the slider.
Why does my controller select the wrong menu option?
A hidden pointer triggered by the touch button stays hovered over a different entry. Stick to one input method per menu, or move the pointer deliberately instead of switching back to the d-pad.
Fishing does not work — is it a bug?
Confirm you finished the quest that teaches fishing and are at a valid spot first. If both are true, you are likely hitting the reported failure, which Mac players describe most often.
Why are all my synthesis options greyed out?
Usually a missing ingredient or level requirement that the interface never states, not a bug. Free storage space and check species rather than quantity before assuming it is broken.
Does the demo run on Linux or Steam Deck?
Players report it running on Linux without compatibility tweaks, but there is no Deck Verified badge and the demo is officially a Windows build, so treat it as unsupported.
Where do I report World of Slime bugs?
The official Discord is where TEAM42 is collecting demo feedback, with the Steam discussion hub as a secondary channel. Include your OS, input device, and reproduction steps.
