Where to begin... the game is completely unplayable in its current build and shouldn't even be uploaded. As far as I can tell, there is ONE scene in the game at present: A lackluster blowjob scene with a default human male, when you attempt to get into the city for the first time. Here's a rundown of what you can expect from the game after that point.
Step 1: Enter the city, go to the right until you find the stairs leading down and head along until you pick up the amulet. Neneko will discover that her brother Shoto has gone down INTO THE HOLE and tells herself that she should find the most powerful person in town to help her.
Step 2: Naturally, you head to the blood mansion where you are greeted by a maid who clearly knows about your brother. You fight all the maids, collect keys, and eventually find a vampire lady passed out on a chair. She won't talk to you unless you give her "wine". You pick up the wine, and try to talk to her, and the game says NOT AVAILABLE IN THIS DEMO LUL and she doesn't give you the key or do anything, so you cannot access that sex scene, nor the rest of the manor.
Step 3: After wandering around for hours, you may discover that in the area back outside the city, there is a potion hut. Talk to the witch, then break into her basement. Follow her instructions and talk to some more people to get a quest to 'supposedly' get you into the hole. Finally. But you have to slay a Kirin. Head to the east, talk to boat granny, head to the temple, solve dumb puzzles to get to the end. Here you may struggle to figure out how to get through. You have to wander around in circles next to the statue covered in gunk, until the three spiders DECIDE to spawn. Sometimes, they never spawn. But you have to kill all 3 to progress. Then climb the ladder, after meeting the Kirin in front of a chest, and pulling a lever on the bottom floor. Apply the lever piece to the broken lever on the top floor, dodge past the bubble statues, and make your way to the "door" at the end which looks like a piece of stone on the wall, cut in half. Enter the room for the best boss fight of all time, the glitchy and retarded Kirin. It will teleport around spawning bubble trails which deal 2 hearts of damage to you. Attack it once at the end of each trail. Sometimes, when teleporting, it will teleport onto a wall and become trapped forever, forcing you to load your save. After dealing 10 damage to it, it begins to use two trails per attack before stopping. After dealing 5 more damage to it, it enters its ULTIMATE FORM, glitching out of the map to use endless attacks that can't hurt you, but you can still somehow hurt IT when it's out of the map. Killing it will give you one, or two, good equipment items but GUESS WHAT, NOT THE HORN YOU NEED FOR THE QUEST. So, naturally, you can try again and again to kill it in a place where its body spawns ON the map, hoping for a better result. This will never happen. I've killed it on the walls, under the floor, over the floor, in the tree. Even if you manage to catch it while it's stood on the ground normally, its body sinks into the floor leaving just the head poking out. You cannot interact with this corpse, except to attack it, but it has infinite health as a corpse anyway. There is NO WAY in the game presently to get this horn. Quest 2: Also impossible.
Step 4: Wondering now if there is ANY content in this game, at all, let alone porn, you now head to the guild. You can go fishing, plant crops, kill bats, get a map, all of which are useless and time consuming. There's a quest to discover who is stealing food from the warehouse at night. Head to the warehouse at any point during the night and you will see nobody and nothing will happen. Enjoy. It seems that you need some ability to allow you to get into rat holes to enter MANY different places in the city. From what I've seen so far, this ability doesn't currently exist in the game, so good luck doing anything in the city, at all.
Step 5: You finally realise there is one h-scene in the game, no quests that can be finished, a 5fps framerate, an awful combat system and no way to get into the hole - The main premise of the game
Step 6: Uninstall
Seriously, I've played this over many different versions and it just updated to 6.0.2, but is still COMPLETELY unplayable. It's beyond a joke. Do not support this game unless they actually make it even 1% playable.
