Fantastic and simple fun
The graphics were old school and decent. The dragon sprite though seems a bit familiar, not sure what game I played on here years earlier that had a similar looking dragon, maybe How to Raise a Dragon?
The sound effects seemed fitting enough but I think there could have been more variety for weapon and armor sounds rather than one sound effect being used. The music was also decent and fitting for the game.
The game play was simple and is a strategy game as well since you need to think ahead a little to survive longer, Divine Sword will help to take care of dragons with ease as they have really strong attacks even with good armor equipped.
Overall, fun game, I just recommend changing sounds if you ever do anything with this game again someday.
