1. While I think all dialogues are presets I am not 100% certain, so just to make it sure you should exhaust the dialogues of all interactable NPCs every day(don't think it as a hassle, they're great to listen!).

2. Play on easy, there's no need to make your life harder in games like this.

3. Out-of-an-act dialogue choices mean nothing. Choose whatever option you like.

4. You need to collect all stickers for a final achievement.

When you're on stage, there are 5 different genres you can lead the act toward to:
The game will award you with a sticker of the genre you chose most at the end, so choose your options wisely.

There are bonus stickers for each act, which requires you to choose specific options, on what these options are, consult the images below.

Stickers you can get in acts are as follows:

Act 1 - A Roaring Growl

Act 2 - Statue Sok

Act 3 - Once Upon a Jester


On the rest of the stickers, read the walkthrough section below.

Day 1
After you finish your first act, you'll be at campfire with Sok roasting a marshmellow.
This is your first missable achievement, you need to roast the thing just right.
Here's an image of a 'perfect smikkel'.



Day 2
Exhaust the dialogue of Hak, the vendor. He'll give you a sticker that looks just like him.


Talk to mayor and listen to his Bettely Beth song to earn another sticker.


Cross the bridge, and interact with the crank behind the talking, walking tree, a frog in a bucket will descend from above, and you will earn a tambourine sticker


Day 3
After the show, you'll be roasting a frog this time. Roast it till you pop it.

Day 4
Immediately go left to start a monologue next to lake, but you'll not be alone this time, a talking fish will appear granting you a fish sticker and the achievement(and a song... but you don't really need this).


Talk to Poi Poi, the brown bear for the tree branch sticker,


And Boom Stam, tree for the mug sticker.


You should have a complete green sticker sheet after this.

Day 1

Approach the clown all the way right. He'll throw you to the ground blocking your path, and you'll earn a castle sticker.


Day 2

No stickers or achievements this day.

Day 3

Karaoke day. Talk to Hofnar to get a sticker of... a hotdog with arms and legs attached.


The main activity this day for you is a radio show. and you can't afford a mistake on this as it's tied to an achievement and stickers. The initial questions doesn't matter. But the caller songs you need to nail it right. It is super easy, but don't make mistakes.

If you did everything correctly, you'll earn 4 stickers in total:

And an achievement:

Day 4

Talk to ice creams selling ice creams for a ice cream cone sticker.


Day 5
Talk to Pesto Control right in front of you to hear a good song. Earn an achievement and green hood with a lantern sticker after.


Go down the stairs, talk to Bettely Beth to hear another song, and get a purple blob sticker.

A short interlude chapter with no acts.

Day 1
Talk to Frankenfrog, the only loitering NPC in the area and keep listen to his accent till he mentions a witch to receive a witch hat sticker.


This should complete your collection for pink sheet.

Day 2

Before leaving Woudwoods, after picking a pet, Jan gives us a moon sticker thanks to Sok asking him about it.

Day 1

Nothing on this day...

Day 2

...and the day after. But you should at this point try to unlock the Rocketship sticker.
To earn it, select the purple sheet and frantically spam your directional keys selecting different stickers in that sheet. I say again, you're supposed to do this after selecting a Stickervel, not before. if you're shuffling the sheets up and down, you're doing it wrong.


This should be the last sticker of purple.

Day 3

Talk to Freek the fisher for the last time to get an achievement. Bye bye, friend!

There's no missables in the final act, as you play the rest of the game to its end, you'll get both achievements:
And

Replay the game and get stickers you missed in your previous playthrough, and you'll eventually earn:
Unlocking all achievements of this game. Congratulations!
