Bought and tried it. It's kind of unfortunate that this one might be a miss compared to their usual fare because the gameplay loop is raising monsters, using them in a chess-style match and making sure to fuse them when their lifespan is about to run out which can get a bit boring after a while at least for me. Not helping matters is how there's definitely less scenes especially compared to their previous DM Darkness works

One wonders if a Plus expansion might make this much better
