I love it. Stylistically it has always been my fave Caver. I love the whole emo kids with psychic powers mixed with the military vibe of the enemies. I was always a bit gutted that the semi follow ups went down the “fairy” route.
On a general shmup note, I know this kinda contradicts what I said above but I largely fucking despise the trend for kiddy manga characters in a lot of more recent shmups (thinking of stuff like Caladrius Blaze etc). Even the remake of Psyvariar managed to crowbar some kids in. Bah.
edit: basically more games need bald middle aged men as characters.
