The fourth 24 Hours of Inform contest ran from the 9th to the 30th of September 2009.
The required constraints for the entries, provided by James Wallis, were that:-
Two entries were submitted:-
In an Hours of Inform contest, each contestant attempts to write a complete text adventure using the IF-language Inform (any version you like).
The only time restriction is that the contestant must spend no more than twenty-four (non-consecutive) hours on the actual writing and programming. Standing around in bus queues percolating game ideas doesn't count towards the limit, nor does background research, brushing up on Inform, or sleeping.
All entries must conform to the given constraints. This is ostensibly to stop people starting early or submitting old projects, but also gives an interesting level of coherence and comparison to the contest.
