Game description
Bernard, Josette's late husband, still very attached to the hold he has over his wife, cannot leave her alone, even in the afterlife. Desperate, she calls on her loyal friends, Halima and Dorothy. The three widows then embark together on a quest where each will have to face her past and exorcise their respective husbands.

"How to exorcise your husband" is a short puzzle game where you follow three old ladies in their impossible quest. You will have to face the ghosts that haunt each protagonist's past. Armed with special ghost-hunting musical instruments that they ordered online, you will have to fight each husband by solving a series of puzzles.

Each level will require you to find the ghost's position in the grid. Trap it using the anti-ghost device. And finally, destroy its ghostly energy by positioning each protagonist at the right distance, so that the wave generated by their instrument resonates with the ghost's paranormal energy.

Theme interpretation
Waves in the physical sense produce a whole range of phenomena. We have tried to reproduce some aspects of wave propagation in space while simplifying everything to produce interesting gameplay. In this game, you must position wave emitters in a grid so that the result of the superposition of these waves, as measured by an observer, corresponds to a well-defined pattern. In the end, only the idea of signal phase shift as a function of distance remained, such that it is possible to create an intuition about what each interaction brings. But we still use the 2D wave solver as a cool overlay.
