This game is so hardcore that it combines action games with math. The graphics quality and control of the game need to be improved.
First you need to use bow and arrow, sword and shield to defeat the enemies in the castle, you can use shield to defend against enemy attacks and you can also use roll to dodge. Eventually, you will be given three scrolls. The contents of the scrolls will guide you through three detailed mathematical formulas.
Next, the game changes to a straightforward way of playing. You need to use the mathematical formulas to calculate the landing point by the weight and speed of the bow and arrow to detonate the explosive barrel to defeat the enemy. You also need to calculate the location where the cannon's shells will fall to defeat the hordes of enemies.
If you like learning math from games, this game is great. But I'm not good at math, and this game is a nightmare for me.
