You cannot swim whilst you are underwater. You cannot jump on any enemies in the game. If a Timer Item appears whilst playing in the level, grabbing it will reset the hourglass. If you don't have enough hearts and the timer flips again, you will have to use a Revival Medicine or die.
If you have half a heart, and a full heart you will lose half a heart, and half of the full heart. If the timer flips over, you will lose a heart. The game has a timer on the left side of the screen. Whilst checking your controls, make sure you have one button assigned to the Credits. In order to start the game, you actually need to insert a Credit (stupid idea), and the Button cannot be the button used to insert credits. You'll need to assign a button on your controller to wiggle. I strongly recommend that you change the controls on all 3 games, since you may not like the controls the game has automatically placed in. SVC: Monster World contains features which you can use to change the games, such as choosing the American, European or Japanese Versions of the 3 games, changing the Background Themes, Screen Size and you can save your games anywhere you want, and reload them anytime you like. And also the games are known to be time consuming and repetitive. Possible reasons include that it contains games that are not popular worldwide. It is the least popular package among the SVC Games to date.
The package has been received Mixed Feedback. The two of them are on a quest to find and rescue someone in a plea for help. In the game you play as a girl named Asha, who is assisted by her small companion Pepelogoo. Monster World 4 is the last game based within the Wonder Boy/Monster World series to date.
