To enjoy this game the most, please first read the short (very short) story of the same name by Jorge Luis Borges.
So I played through this. Tried to, anyway. There was no really clear direction of the game; when you played it, you did not ever know what to do.
But with that aside, it was still a very original and creative product. So I'm giving it a 3 for effort.
The House of Asterion is certainly a maze. Essentially it uses many copies of boards and links them together rather confusingly so that rooms can lead to themselves, or other rooms that you didn't think they originally lead to. You will go in circles. Eventually as you wander you will find keys, and you'll wonder where the heck the doors are. Well, I did, I never found the doors. The graphics are sparse, with typed labels for "Living Room" and "Stairs", which are the only clues as to where you are, cause there are no objects in this game (except for the endgame object.)
This will hold your attention for a little while, and if you manage to beat it, well, your reward is beating the maze.
I recommend turning the speed all the way up before you start, you're going to be doing a lot of running.
