You can have 6 characters at once in battle.
Characters can equip 2 weapons at once, and you can switch seamlessly each turn. Each weapon does its own thing
Bow - range
Sword - close
Knife - can sometimes do multiple attacks (maybe only from behind?)
Hammer - swings in a circle, hitting everything friend or foe
Axe - no idea, maybe just really strong
You can also equip books to learn magic, so anyone can learn magic. You can buy any spell from a shop. When you use a spell long enough, you learn it, and dont need the book anymore, but you get a bonus if you hold onto it.
You can only equip 2 items for use (a book can fill one slot).
There are treasures on the battlefields, not hidden. There are also sometimes items that you can examine that unlock a bonus battle map.
There are multiple endings, but unsure what decides them. I had to make a decision early on, but no clue if it affected anything, so I saved it in a separate slot.
The game autosaves after each fight, but you can manually save in 10 slots.
Buying and Selling equipment is hassle-free. You can tell what is stronger by green/red arrows.
