I don't get where the hack n Slash comes from, the map has a full random battle system. I do however feel that the monsters at the start are very easy. I have slowed the game down a bit, the area after the demo the game gets a lot harder because the normal enemies have +5 ups and take at least 3-4 hits to kill, but it really depends on your level. They also do a huge number on your health so you'll find yourself needing to heal after every battle.
Quite honestly I'm more focused on getting the map done then making the game extremely hard or what-not, after I finish the map I'll go back and maybe a harder version, etc. etc.
As for the terrain, I personally think it's very good but I guess you all have your individual opinions. Then again I didn't do the terrain so direct all complaints to Ryu.
None.
