CAMPAIGN DESCRIPTION:
Yoshi has been kidnapped by Big Boo! With Mario and Luigi nowhere to be found, it's up to the Survivors to infiltrate the Vanilla Ghost House, defeat the boss, and rescue him.

Do not play this with bots. You can technically complete it with bots, but I'm warning you, it can be frustrating.
They are just not programmed to deal with custom bosses or platforming elements.

DEVELOPMENT NOTES:
This was created in a month for a contest on another website. Although I worked hard on it, I had to rush my way through making it in order to meet the contest deadline. This probably reflects in certain aspects of the campaign.

I admit it was my first Source map, and I can do way better than this now. But I am still making it available as an example of how much I have improved.
It is also still open to updates and improvements in the future.
