Romancia: Dragon Slayer Jr.

This game exists in two editions, one for the MSX1 and one for the MSX2 with better graphics.

In Romancia: Dragon Slayer Jr., you are a young warrior whom the king sends on a mission to rescue a lost princess. You must leave the town and enter the dreadful monster-infested catacombs in order to complete your quest.

The game is a departure from Dragon Slayer RPG-oriented gameplay style. It tends more towards medieval-themed platformer action. The hero has hit points, can buy items and weapons, use magic, and stay in inns to recover health. However, instead of receiving experience points and becoming stronger, you simply must attack quicker (by bumping into your opponent on platform levels) and jump higher.
