Makakara is a pretty solid RPG for the PC-8801mkIISR and above. It has an overworld where you can explore a decent variety of areas and find enemies to fight. Engaging in combat changes the display as you move into an overhead view. The combat takes place in real time.

The artwork is nicely done, however, I think they may have used an 8-color base, perhaps to maintain artwork that could work on the X1, and then just added shadowing or other subtle effects for the PC-8801 version. The underworld has a consistent appearance, at least so far. The dungeon layouts certainly change, but they all have that bright orange look to them.
