需要擊敗頭目來取得共七顆水晶，每顆水晶都有不同的能力提升。首先，一樓的頭目是Homa。打敗後，可以啟動接關祕技。接著來到二樓，這裡有兩顆水晶。擊敗Doma後，會拿到第2顆水晶，可以增加發射的氣泡大小。二樓的另一個頭目是Barukama，擊敗他後可以獲得第3顆水晶，會擴大氣泡的攻擊範圍。

接下來，來到三樓，打敗Blue Doma就能拿到第4顆水晶，能夠快速發射兩個氣泡。三樓還有另一個頭目是Red Homa，雖然擊敗他後拿到的第5顆水晶不會增強任何能力，但這是一個必須完成的過程。三樓的另一個頭目是Red Barukama，擊敗他後可以拿到第6顆水晶，這顆水晶和第3顆一樣，能夠擴大氣泡的攻擊範圍。打倒頭目Kama後可以拿到第7顆水晶，可以快速發射三個氣泡，接著就可以移動到4樓。

遊戲主要挑戰來自於探索和解謎。城堡由四層樓組成，每層都有不同的房間和敵人。需要在每個房間中尋找鑰匙和門才能繼續前進。有時候，需要擊敗特定的敵人或完成特定的任務，才能獲得通往下一層的鑰匙。眾多隱藏的房間和道具，增加遊戲的深度和可玩性。

Key Items and Power-Ups Players can collect honeycombs to increase HP, notes for money to buy important equipment, and music boxes that allow them to play more tunes. Hidden items include a saw to cut wooden windows, an oil lamp, a fireproof vest, spring shoes, a medicine jar, and a hammer.

Bosses and Crystals In the game, players need to defeat bosses to obtain a total of seven crystals, each enhancing Milon's abilities in different ways. The first-floor boss, Homa, grants the ability to use the continue cheat. On the second floor, defeating Doma grants the second crystal, increasing bubble size. The other boss on the second floor, Barukama, provides the third crystal, expanding bubble attack range. On the third floor, defeating Blue Doma grants the fourth crystal, enabling rapid firing of two bubbles. Defeating Red Homa on the third floor grants the fifth crystal, although it doesn't enhance any abilities. The other third-floor boss, Red Barukama, provides the sixth crystal, also expanding bubble attack range. Defeating the final boss, Kama, grants the seventh crystal, allowing rapid firing of three bubbles, and unlocks the fourth floor.

操作簡單而直觀。通過方向鍵來進行移動，持續按左或是右就能往該方向奔跑，按上就能進入門內、窗戶或是特定的牆壁。A鍵用於跳躍，按的越久就跳的越高，後期拿到飛艇時，按A鍵就可以進行漂浮。B鍵用於發射泡泡，攻擊敵人或是破壞石頭，按B鍵的時候再按下就能再下方射出泡泡。按Start鍵來開始或暫停遊戲。Select鍵則是切換到選單狀態。

泡泡是主要的武器，能夠攻擊敵人、打破磚塊。遊戲的過程中，需要探索城堡的各個房間，裡面都有敵人和各種謎題。某些磚塊中隱藏著重要的道具和通道，須注意如果在城外逗留太久會出現閃電攻擊，需要用泡泡打掉。

Gameplay and Controls The gameplay is simple and intuitive. Use the directional pad to move Milon, holding left or right to run in those directions. Pressing up enters doors, windows, or certain walls. The A button is used for jumping, with longer presses resulting in higher jumps. Later in the game, after obtaining the balloon, pressing the A button allows Milon to float. The B button is used to shoot bubbles, which can attack enemies or break stones. Pressing down while shooting with the B button will shoot bubbles downward. The Start button begins or pauses the game, and the Select button switches to the menu.

Weapons and Exploration Bubbles are the main weapon, used to attack enemies and break blocks. Throughout the game, players must explore various rooms in the castle, each filled with enemies and puzzles. Certain blocks hide important items and passages. Staying outside the castle for too long will trigger lightning attacks, which must be countered with bubbles.

關卡中隱藏一些祕技和彩蛋。1.只要打倒第一關的龍並拿到水晶球後，挑戰失敗時，按左再按開始就能接關。畫面會從原本的Password變成Continue。2.在日版遊戲中，可以進行連發按鍵測試。在標題畫面出現時，快速按A或B鍵，按下的次數會顯示在螢幕的上方，最多可達326次。停止按鍵時，數字會自動歸零。3.當玩家連續全破兩次遊戲後，會出現秘密訊息 "This is the end of Episode 1. See you again!"。4.在第三層的壁爐室中，進入後再離開商店，16個石頭錢就會激活。重複這個操作，每累積到256元時就能得到額外的生命血量，效果和蜂巢一樣，最多可以增加16個血量。但一旦退出房間，累積的次數就會歸零。

Several secrets and Easter eggs are hidden in the game:

After defeating the first dragon and obtaining the crystal ball, pressing left and then Start after failing a challenge activates the continue cheat, changing the screen from Password to Continue.

In the Japanese version, a rapid-fire button test can be performed. At the title screen, rapidly pressing the A or B button will display the number of presses on the screen, up to 326 times. The number resets to zero when button presses stop.

Completing the game twice in a row reveals a secret message: "This is the end of Episode 1. See you again!"

In the third-floor fireplace room, entering and exiting the shop activates 16 stone coins. Repeating this process, accumulating 256 coins will grant an extra life, similar to the effect of honeycombs. The count resets upon leaving the room.
