Reads everything, hunts amber; “in some cases closer to 12” Dev
What adds time: reading notes and listening to tapes (optional — almost all narrative can be skipped) Dev, getting lost in the big caverns, and retrying chases. What saves time: skipping cutscenes and lore, and knowing the codes.
How many levels?
Four, matching the “Finish Level 1–4” achievements Official. They are long, mixed-pace levels rather than short stages; see the walkthrough for what each contains. Two days after launch, 14.4% of Steam players had finished Level 4 — consistent with a game most people need several evenings for.
100% completion
On top of the story you need every amber, note, audio tape and stuffed animal (five collectible achievements) plus a handful of quick misc ones. No one has published a reliable 100% time yet; we'll add one once enough players report it. Use the achievement checklist to track it.
Replay value
Beating the game unlocks New Game Plus with four modifiers — body-cam, slippery surfaces, die-if-you-stop and low gravity — which can be combined Dev. Low gravity in particular lets you break sequence. WDR also thanked players for demo speedruns Dev, so expect a speedrun scene.
