I have 8 locations, and 4 puzzles.
And a large word count. I've labelled mine first as a visual novel because the amount of verbiage. :)
I'm also worried that the puzzles may be too difficult for this audience, so I'm doing my best to build in a hint system. I'll find out how that works.
My game will take about 60 - 70 minutes to complete? I'm still trying to gauge how long it will take.
How about others? Since this is my first game jam, I don't know how long others usually make there games.
