Planning

After the research I created a simplified version of the representations of the elements and connections, with the objective of visualizing how the connections would be arranged and how their format and complexity would affect gameplay.

HydrogenH
OxygenO
Molecular HydrogenH2
HydroxylOH
Oxygen GasO2
Ozone GasO3
WaterH2O
TetraxygenO4
Hydrogen PeroxideH2O2

Gameplay Design

The complexity of the bonds and the number of atoms per bond increases to make the game harder. This also makes it more difficult to avoid unwanted atoms or skulls that lead to the loss of the bond, since the greater the number of atoms in the bond being handled, the larger the hitbox is, the easier it is to get hit.

Educational Design

One of the great challenges of the project was to make the game fun and maintain it's educational value. I made sure to use chemical bonds that actually exist in chemistry to ensure that visual representation of each element and bond were faithful to the scientific representations.

Example: Water

H2O
Chemical formula
Molecular model
In-game representation

Another example of fidelity with scientific representations is the number of bonds that each element can form, these bonds are represented by the lines between two atoms, in this case hydrogen (H) can form one bond, while oxygen (O) can form two bonds.

Oxygens form a double bond

Each hydrogen forms one bond while each oxygen forms two bonds

Even though they do not form all the possible bonds, the number of possible bonds is still represented


Level Design

In the design of each level I was concerned with always introducing something new, both to maintain players engagement and to divide all the content properly and not overload them with information.

Levels

What's new at each level:

level 1: Bonds

level 2: Bonds with moving atoms

level 3: Dodge other atoms

level 4: Bonds with another element (oxygen)

level 5: Multiple bonds and new bonds

level 6: Dodge atoms with skull

level 7: New bond and 3 atoms bond

level 8: New bond

level 9: New bond and 4 atoms bond

level 10: New bond
