I'm giving this game a 5/5 right off the bat, because the music reminded me of good earthy and natural games I used to play. It almost reminded me of Harvest Moon.
Cave of Trials level 5 is done by loading your forces with archers. I used centaur archer, succubus, dwarf engineer, mermaid, then goblin and phantom armor as melee. All maxed of course.
