I'm around an hour into the game (the first big boss fight in the ruins) and I'm pretty impressed with what I've seen so far. The world is interesting enough for a h-game so I don't mind a lot of the talking plus the art looks pretty decent so far. I also really like the map designs so far and the ruins were fun to traverse.
On the other hand, I'm only an hour in and I've come across so many problems I don't know where to start. I've already read through the comments so I know everyone has pretty much touched all the major gripes like janky text speed, extremely frustrating combat and how the game feels extremely slow. For the last point, the game being too slow, it feels like nearly every part of the game is made to slow down player progression and as a result, the pacing feels horrible. Nearly every small action takes an unreasonable amount of time. Fishing is slow. Warping in the ruins is very slow. Talking is slow. Combat is slow. Even the fact that the game only lets you save at save points makes the game slow since if you die and haven't saved in a while, you need to repeat all the stuff you just did. Nearly every move the MC has early on feels slow. Her first damaging skill only lowers enemy attack, it doesn't actually end the fight faster. The rest of her skills are just buffs that end up resulting in taking a turn to buff yourself. As a result, she does poor damage and its impractical to defeat an enemy with average health with her. The mage party member has awesome damage but her downtime is awful. When I ran into the first boss and saw his health pool of over 700hp I nearly bailed the game right there. Even worse, it calls for more allies with decently high hp and can resummon them when they die. You can ignore them but one of the summons can silence your mage AKA you're only source of good damage. AND THE SILENCE LASTS FOR 5 FUCKING TURNS. You can't even use the mage's only multihitting move, lightning, because it sucks against the boss and the enemy that silences you, and that's if the damn lightning hits in the first place. For a move that costs so much and hits twice, it misses way more than it hits. Besides that, the encounter rate is pretty high which I believe wouldn't be that bad if you could speed up the battles.
Ultimately, the game has a lot of room for improvement but what I wanted to point out was that if this was just a normal game made by someone or a group on the internet, it would be fine. But as a hentai game, all the faults gets amplified massively. The main reason someone would pick up this game is for the porn and I've heard that there's a decent amount of it in the game so far. The problem is that I've only seen one scene and the second one doesn't feel anywhere closeby. Pacing is very important in h-games since the scenes need to come at a steady pace so that the audience doesn't lose all the horniness that they've accumulated because they were too busy fighting the game mechanics. For me, I started the game with high hopes and the first scene came pretty late because the game's pace felt so slow even though I wasn't actually doing much. By the time I reached the ruins, I lose pretty much all sexual interest in the game. After my first defeat by the boss after fighting it for over 10 minutes, I just closed the game and went to exhentai.
Overall though, from what I've seen so far the game has a lot of potential and I'm looking forward to playing the rest. Hope the devs take this constructive criticism well and use it to refine the game.
