Legend of Heroes: Trails into Reverie - Second Stratum

The second stratum is much larger than the first, and there is a new mechanic where a paradise-like area is available for you to enter. It will contain different enemies than where you currently are at, and seems to even have its own special Poms. Otherwise, we have the bigger than normal enemy encounters here and there as we make our way through, but there is a mirror match mid-boss and then a boss fight at the end that definitely seems to reinforce the parallels between this game and Sky 3.
