This PunyInform game was made by a parent-child team, and it's pretty complex for a game made that way, but not as complex as most finished games made for competitions are.
Your pub has been cursed by a ghost until you make a drink for them. Each component of the drink is found by solving a different puzzle.
The number one thing the game could use is more feedback from testers, who could have caught things like undescribed objects, exits not listed in the room description, variations for trying to figure out what to do with the shaker, etc.
