Level Greybox
iteration 1
iteration 2
-
adjusted spacing to be horizontal due to length of slinky dog
-
regulated distances between obstacles
final iteration
-
expanded proportions, varied obstacle heights,
-
planned more detailed player path from playtest
-
added alternative challenging route

Early Stages
Level Drafts to envision levels before grey box
(Emkay)
(Grams)
Greybox Stage 1
Practice arenas to explore direction
1. Walled and clustered rooms and hallways
2. Open air level, blocky floor/walls of different elevation.
Greybox Stage 2 - Single level
3 interconnected Labs each with unique mechanic.
The LABS
LAB 1: Gooey Lab
-
Goo that slows player movement
-
Basement secret lab
LAB 2: Frost Lab
-
Catwalks
-
Frozen region that freezes pizza
LAB 3: Spiral lab (Bill)
-
4th floor elevation
-
jump pads
iteration 1:
-
Too clustered,
no relief after tension
-
We want SENSE OF SPEED
iteration 2:
-
Single map, a loop with all labs, lack of player choice
-
Onboarding is a challenge with 1 level.
iteration 3:
-
Linear tutorial hallway from the central hub.
-
More alternative routes between labs.
Greybox Stage 3 - Multiple Levels
We pivoted to mutiple levels to curate a smoother player learning curve. Each distinct mechanic is its own level.
Frost Level
Simple Level
Tutorial Level
Spiral Level
Bonus Level
Gooey Level
only 1 pizza and timer to learn base loop
to master 2nd pizza and powerups
to introduce microwaves and reheating
to utilize jump pads
to avoid environmental hazards
ALL together
Gooey Level Greybox
Expanded map
More open space
>>>>>
Player move more freely
Sense of rushing through with speed
Height 1
Height 2
Height 3
Goo
Catwalk
Resources & Target Distribution
Central Region = Resource
Outerbound = Target
Easier to replenish pizza
Encourage player to zoom straight across the map
