I remember playing around with an engine similar to this for my senior project.

Downloadable versions for PC and Mac since the music made the file sizes fairly large.


It's more of a mix between the old King's Quest games and Monkey Island though, since it's keyboard only. And also buggy as hell since it's all AS2.

I'm excited to see where your engine will go.
