Powerful Jot
Fully upgrade Jot's abilities.


To upgrade abilities, you need to collect enough lightbulbs. It can be obtained by exploring the map, or by hitting objects in the environment (including trees, bushes, pillars, etc. Objects in both 2D and 3D environments can be hit). Once you’ve gathered enough, you can purchase upgrades from the merchant, who appears along the main story path, so there's no need to search for them specifically.

During the game, you don’t need to thoroughly explore every inch of the map, as resources are quite abundant. By Chapter 7, I had already unlocked all abilities.

I will list the locations of the Glitchbird and Art Scrolls in each chapter below.

Optimistic Explorer

At any point when you're in the 3D world, you can jump off the table to obtain it (go ahead, you won’t die).

Catch Floatio on your first try.


In Chapter 4, you will reach a bridge underneath where you can find a fish flopping. Interacting with the fish starts a Minigame where you must grab it by pressing a prompt. If you miss it on your first attempt, Quit the game and get back in to find yourself at the start of the room on the bridge.


Huge Bridge
Rearrange a sentence to make the bridge huge.


During Chapter 4, you will come to a puzzle room where you can find a broken bridge next to some singing frogs. You must change the time of day during the puzzle and replace the words "Broken" with "Huge" from the previous page to unlock this achievement.
