Wonder Boy in Monster World — About this game
Explore Monster World, speak with residents and fight monsters along the way. Use jumps to explore the terrain and attacks to deal with nearby monsters. Listen to residents and read signs for clues before deciding which route to investigate. Check the next landing before jumping and judge the distance before attacking. Leave room to retreat rather than chasing an enemy across a gap. Look at the terrain and the enemy together before choosing the next move.
