Well, looks like my wish for what the mini boss would do was granted. I love it. Also, careful after you beat the boss. There's a bug where if you beat him, and then lose to one of the zombies he summoned, it'll proceed to the first part of the H-scene, and then the next part, you instantly die again and start the loop. So basically, you soft locked the game.
Also, does anyone else have any sound lag for certain things? Menu sounds and attack sounds are a bit delayed, but H-scenes seem pretty synched.
After fighting the mini boss a bit, I gotta say that the battle itself, at the moment, is made where you can feasibly not get a game over from the boss. With the first boss, if you got caught twice, you lose. But here, no matter how many times you get caught for the H-scene, if you can escape fast enough, you can keep going and not accumulate any stacks of zombification. I think there'd be more of a threat from the boss if either you got a stack of zombification when you get caught for the H-scene, or if the boss could fight back besides summoning zombies, like shooting projectiles that cause zombification. Speaking of which, if you stand next to the boss, he can't do shit if he summoned all the zombies already, besides teleporting if you hit him enough.
