Today, I launched Valkyrie drive Bhikkhuni, and played it 3 hours without any pause. It's quite rare for me to play for that long, the last it happened was for the Blue Reflection games... The game is... mid on nearly every point, but it's fine and agreable to play nonetheless. A few technical difficulties at launch, but now it works, which means I can play this glorious unashamed safe gooner game without any shame !
I knew the franchise before testing it because I've watched the mermaid anime a few years ago, and read the manga adaptations, i'll re-reading them after finishing the game.
