Astyanax or however you pronounce it is basically a clone of Legendary Axe on the PC Engine. The gameplay is quite simple, you run from left to right bashing skeletons over the head with your Axe, making it to the end of the stage will often lead to a boss. The first thing I noticed when going through the first stage of the game is the sprites are just massive. The main character is at least doubled in size over other action platformers on the NES.
