Does look like a good hack 'n slash with RPG elements.
Yes, it's an amazing 2D beat em up / hack 'n slash game with a smooth animation.
Made by Treasure, SEGA's second party game company who made Gunstar Heroes, Dynamite Headdy, Light Crusader, and Alien Soldier.
A sequel also has been made for
Gameboy Advance entitled
Advance Guardian Heroes.But due to the inferior hardware, it's not as smooth as its Saturn prequel.
Sometimes in the game we'll get frame rate problems. Still fun to play though.
