An old-style pixel 2D platformer who becomes an apprentice swordsman, confronts dragons and rescues princesses. You can easily enjoy your adventure with simple operations such as jumping and dashing attacks. Enjoy the world of charming enemy characters, items that grow apprentice swordsmen, and a simple and nostalgic game world. ◆ Story ◆ This is a certain kingdom. The jewel that contained the dragon was stolen by an evil swordsman. Unleashing the dragon from the jewels, the swordsman gained immense power and hijacked the tower of the kingdom. The king managed to escape, but the princess was captured. The king sent many troops to the tower to retrieve the princess and the jewels, but none of them came back alive ... As a last resort, I decided to entrust everything to the "apprentice swordsman," the descendant of the legendary swordsman who once contained the dragon in a jewel. Many objected to sending the "apprentice swordsman" to the tower, but the king felt something. Find the legendary equipment that the legendary swordsman once wore, and regain the jewels and princess. The "apprentice swordsman" invaded through the hidden passage of the tower on a full moon night. ◆ Game overview ◆ The purpose is to collect the legendary equipment and keys in the dragon tower and defeat the demon swordsman and dragon. Also, a princess is captured somewhere in the tower. The princess can clear the game without rescuing, but rescue is required for the true ending. There are two types of attack methods, "dash attack" and "trampling". -Dash attack ... Effective against all enemies, but also damages the player. -Treading ... (an attack that jumps and tramples the enemy's head) has some effects, and the player is not damaged. When you get an item, it will be displayed in the upper left of the screen and will be equipped automatically. When the life at the top left of the screen runs out, it will be respawned at the previous checkpoint (the position of the last coin picked up). "START" ... Play the game from the beginning. "CONTINUE" ... Select the saved area and start. ◆ Operation method ◆ ■ Touch operation Move left and right ... Virtual stick Jump ... Virtual A button Dash attack ... Virtual B button ◆ Item ◆ ■ Legendary equipment Boots ... Move faster, increase the distance of dash attacks. Sword ... Attack power increases. Shield ... Increases defense. Armor ... Becomes invincible during a dash attack. ■ Other items Green medicine ... Recovers physical strength. Coins ... When you take a coin, you can start from that place. (Checkpoint) FD (floppy disk)… If you take the FD, you can start from that location even if you quit the application. (Save point) Dragon Jewel ... The game is clear when you get it. Princess ... I'm imprisoned somewhere in the tower. Necessary for a true ending.
