Fairly orthodox RPG as far as RPGmaker games go. It'll only take a couple hours to complete, after which the gallery will be unlocked. Most of these scenes involve restraint and domination, and with some very clean art and a surprisingly decent MTL there's quite some promise here.
The main game mechanic here is the skill tree. After each battle, you gain energy crystals in addition to EXP and materials (basically money). Energy crystals are basically skill points that you then use to Reinforce your two weapons, the sword and gun, which assuming you're not grinding will determine your playstyle. Broadly speaking, the sword tree is much more balanced while the gun tree is all about offense.
In addition to the skill tree is the crafting system. As said earlier, you gain material after battle and also through exploration. For all intents and purposes, material is basically your money. At your base, there is a crafting table where you spend your materials to create healing items and bullets for your gun. Certain bullets are only available after you unlock them through progressing through the game, after which you can craft as many bullets as you want for that type, assuming you have enough material.
Beyond the JRPG mechanics, this game gives H content through in-battle restraints and defeat scenes. Most enemies will try and restrain your character in battle. This occurs when they successfully disarm both of your weapons. You can pick up a disarmed weapon, but it will take your whole turn and give the enemy more opportunity to attack. When both weapons are disarmed, you are automatically restrained.
Quite frequently, you'll get ambushed by enemies which automatically puts you in the restrained state. You can toggle the visibility of ambush points on/off but since they're almost always in spots where you want to get treasure, you're mostly forced into those encounters anyway. At this point, there are a variety of techniques to break out. Each turn you spend restrained, the enemy will attack, grope, and strip you. If all your clothing has been stripped and you're still restrained, then you're fucked, literally. Losing virginity has very minor effects on the gameplay.
This is where my main criticism of the game comes. There's no real challenge in maintaining your virginity, nor are there any benefits like a secret end or any of the kinds of perks you'd typically expect. Nor does the game necessarily reward you for playing like a deviant. At most, losing virginity unlocks new traps that assault you for new H scenes. The worst part is that the in-game dialogue doesn't acknowledge your status. Rather, events happen with the assumption that you've lost your virginity at some point. It's very jarring when NPCs tell you, "We'll keep on fucking you!" while you've stopped all their advances the entire time.
Overall, it's a decent enough game. The game systems are solid but have already been explored and implemented in other, better games. Restraint and defeat H scenes are very outdated, as they only slow gameplay to a crawl which is made worse when they're only way to get H scenes. Finding a good HRPG can be very rough, since there's quite a lot of garbage out there. This game is just decent, there are certainly better games out there if you just keep on looking.
