This walkthrough covers the currently released Days 1–3 demo of Mushroom Oasis, not unreleased future days. It has four numbered bad endings and a neutral story-progression finish. Save before the Day 1 dinner decision, the later reaction to Mychael, and the opening of Day 3 to collect every available ending without restarting each time. Each route below gives the specific selections that control progression; dialogue-only variations are identified separately.
Day 1 – Main Story Route
Start a new game and enter your name and the cat’s details.
Choose either Male or Female for the cat’s pronouns; the story route stays the same.
When you wake at Mychael’s house, choose Pretend to be asleep. or Stay awake. Either response continues.
When asked whether to stay, choose Say yes.
Choose any of Pretty., Cool., or Hot. when commenting on Mychael; these change the conversation but not the route.
At dinner, choose either I don’t eat meat. or I’m okay with meat. Both continue the story.
When you see Mychael’s eyes and must decide how to react, Save 1.
Choose Remain calm. to remain on the continuing story path.
Finish Day 1 and continue to Day 2.
Day 2 – Continue the Story
Load the main-story save after choosing Remain calm. on Day 1, or continue directly.
When the conversation menu appears, select the question about learning to cook: How did you learn to cook?
Read Mychael’s response and any follow-ups you want.
Return to the available discussion topics.
Select How do you have plumbing in your house?
Read the explanation; further plumbing questions are optional.
Return to the discussion topics.
Select What’s it like living in the woods?
Finish this conversation.
After all three topics have been covered, proceed with the remainder of Day 2.
If you want the vegetarian meal variation later, choose Do you have something else? when discussing food; this does not unlock a separate ending.
Continue into Day 3.
Day 3 – Neutral Ending / Story Progression
Save 2 at the beginning of Day 3, after the river incident and return to Mychael’s house.
When you reflect on what happened, choose I was probably just being paranoid… to follow the normal, non-suspicious branch.
When the resulting Flirt. or Goof around. decision appears, select whichever scene you prefer.
Continue through the knitting scene when offered; the knitting choices change the scene rather than the ending.
At the meal, select Grilled cheese, please., Garlic bread, please., or Just the soup, please. according to preference.
You do not need to accumulate suspicion to finish the neutral story.
When you reach the rabbit and mushroom-circle scenes, avoid the Call him out. confrontation.
If offered I-I guess you’re right., choose it to return to the ordinary story path.
At the ending, select Hug him. or Thank him.; either leads to the same neutral progression with a different final interaction.
Read to the end of the currently available Day 3 story.
Ending 1 – Peaceful Slumber
Start a new game or return to a save before the dinner decision on Day 1.
When Mychael asks whether you will stay, choose Say no.
When pressed about your choice, answer Yes. It’s what I’m meant to do.
At the final insistence prompt, choose the purple Yes. option.
Continue to Ending 1: Peaceful Slumber.
Return to the original save for the remaining Day 1 endings.
Ending 2 – You Monster
Load Save 1 from before the Day 1 reaction to Mychael’s eyes.
Choose Freak out. rather than Remain calm.
When presented with the needles, choose Take them.
At the follow-up choice, select Attack him.
Read Ending 2: You Monster.
Ending 3 – Playing Pretend
Load Save 1 from Day 1.
Choose Freak out.
When offered the needles, choose Leave them.
Read Ending 3: Playing Pretend.
Alternatively, return to this branch, choose Take them., then select Listen to him. instead of Attack him.; this also reaches Ending 3.
Ending 4 – Forget-Me-Not
Reach Day 3 by staying with Mychael on Day 1 and choosing Remain calm., then completing the three Day 2 conversation topics.
Load Save 2 from the start of Day 3, or save before the first major Day 3 decision.
Immediately after the river scene, when Mychael has carried you home and given you clothes, choose I should be careful…
This is suspicion choice one. Do not choose I was probably just being paranoid…, because that opens the Flirt / Goof route instead.
The suspicious opening skips the normal knitting options; continue on this branch.
At breakfast the next morning, when asked whether you trust Mychael, choose Don’t trust him.
This is suspicion choice two.
Proceed through Mychael’s attempt to guide you home.
When he stops you from touching the mushroom circle and reacts angrily, choose He’s being sadistic. if this choice is offered.
This supplies the third suspicious reaction needed for the hidden route.
During the rabbit-related confrontation, choose Please..? rather than I-I guess you’re right.
When the additional response appears, select Call him out.
Read the remainder of the confrontation; subsequent replies do not change the result.
Finish Ending 4: Forget-Me-Not.
If Call him out. is missing, revisit Day 3 and ensure you selected all three suspicious reactions and the Please..? branch.
