Studio 10: Scoping your own games concept in AGS

For this term i am required to come up with a games concept which can be implemented into my chosen game engine.
After working with AGS throughout this term, i have become very familiar and comfortable with it, thus it is natural that i use game engine to create my game.
knowing that this games engine is restrited in many ways, i will have to make sure the games concept keeps within these restrictions.
the idea i have is simple (considering the games engine) yet may contain complex interactions giving the user an enjoyable experience.

Concept

Alot of the games pre made on AGS use rooms as the context. i wanted to do something a bit different so i decided to do it within a maze. the character simply has to get through the different mazes , which increase in difficulty throughout. on their way they must collect 4 keys which are used to unlock each passage to the next maze. the purpose of the game is for the hero to get to his beloved who the bad guy has locked away in the final fortress maze. so basically he has to resue her. their will be no combat involved as the games engine does not allow for this. to stop the hero from accomplishing his quest will be the bad guys evil henchman which are scattered on each maze ready to pounce and 'kill' the hero.
