There are a total of 13 effects in LcdDem for Chie to collect, and can be found in various worlds just like in Yume Nikki or any other fangame.
Unlike Yume Nikki or other fangames, however, gathering the effects will do nothing to progress the game (although some will grant you access to certain areas). You only need one effect to complete the game as it leads to collecting some orbs - this effect can either be Sneakers or Dog. Nothing else is required and is entirely optional.
The effects are used by pressing the Shift key.
In the waking world, the effects names change into craft supplies.
Sneakers(スニーカー)EditThe speed effect for this fangame, it doubles Chie's movement speed.
Pressing Shift causes her to jump, though this doesn't seem to do anything, but the useful one is to jump through some gaps of passages. In reality sneakers are a light-blue colored pencil.
Found in Rainbow Tiles World.
Dog(いぬ)EditThis effect gives Chie dog ears.
When you press Shift, she turns into a dog, which is useful for getting into small areas and can jump through gaps like sneakers do. In reality dog effect is actually a brown crayon.
