About Size Matters
In Size Matters, you play a scientist who has accidentally ingested a chemical that makes him shrink every second. You must produce an antidote before you shrink too small, while navigating a laboratory that becomes harder to get around as you get smaller.
Search and navigate
Find ingredients and formulas around the lab. As your size decreases, reaching equipment and ingredients becomes trickier, and getting around takes on a platforming focus: climb onto surfaces where lab equipment and ingredients are located. You can also rearrange the lab to reach what you need. Time is limited, so you must search for missing components while processing ingredients.
Use the lab equipment
Each formula is tied to a machine. Following formulas accurately lets you produce ingredients, which can be used in other formulas or serve as one of the antidote’s three key components. Search the lab for formulas and ingredients, produce all three key components, then place them in the antidote producer to make the antidote.
The equipment includes the Chemical Processor, The Reverter, Code Combiner and Antidote Producer, among other machines. If you shrink too small, the game ends.
Adjust the settings
You can change settings such as your starting height, how many double jumps you can perform and how long the Chemical Processor takes to complete its process.
