As a web developer in a video game association organizing a game jam for last halloween, some of my friends and I said "why not make a JS game?".
We created a story and imagined 3 different mini-games that each member of the team had to develop
Meet Oogie Boogie and run away from him in a labyrinth using yourse mouse.
Do not touche the walls if you don't want to get catch.
Find the door at the end to definitely escape and pass to the next room.
