Host is by far the the project im the most proud of!

It was developed in a month and in the context of a school GameJam at Campus ADN.

I had the pleasure to work with three awesome colleagues and we put our heart and soul into this project. All the assets were made by our team except the sounds and music. 

There are more than 23 Levels and the game is about 60 minutes long as a first playtrough.

«You are a virus trying to escape from a secret laboratory in order to spread a planetary pandemic. However, another virus is faster than you and you must eliminate it at all costs before it reaches the surface before you. To defeat it, you will need to use your viral abilities and use the lab workers to your advantage! Take control of humans and use their abilities to navigate over 23 levels of puzzles and platforming! But be aware, an infected human quickly loses health, your time is running out!»

We designed a multitude of puzzles and plateforming challenges implemented

in a precise difficulty curve and following a structured blueprint to teach, practice and master the game mechanics.

Develop a structured workflow in Game Maker Studio 2 to optimize our time

Organize files in an efficient and easy-to-use way

Iterate through many Ld patterns to make sure we have a  fun and non-redundant gameplay

Scoping the game and the different features to deliver a complete project on time


One of the biggest problems we encountered after several playtests was that if the player did not have the perfect angle to perform a particular jump. The player felt betrayed and would die with great disappointment.


This finding has helped us understand that gamers hate being betrayed and prefer the game to help the player win rather than a punitive gameplay.

We solved this problem by providing a window of opportunity that would give the player a much easier jump in the event of a small mistake on their part.
