Super polished game, good menus, good transitions, good interfaces in general, I don't know how much of that polish is part of the engine, but still, the game does feel pretty good in that aspect
I try to apply the pattern thing into the battles, but it didn't make much difference any fight, I played for 20 men, but I didn't get so see any boss fights. The game doesn't feel like a boss rush at all.
The music was really good, for the type of game / aesthetics.
Not my type of game, but it was fun
