A short but enjoyable game about the titular (!) Naked Female Knight Ulrica that finds herself the victim of an erotic curse. The curse being that any clothing she wears will be magically altered to expose her privates. The entire game is her quest to break the curse.
There's very little in the way of buildup here, the curse afflicts the heroine in the skippable opening, so you start the game fully exposed and you go from there. There's about a dozen outfits that you get that will be modified by the curse; all of them are part of the story in some way. You also team up with a pair of female party members independently during the game for brief side content with each of them.
Art: The translation by Symplexity is very close to 100% if slightly machine-translation like. The artwork is a little basic and under-detailed but mostly appealing. The animation, however, is rare and consits of simple two frames that aren't particularly impressive.
Gameplay: There's combat, and it consists of two generic RPG maker staples; bump-into combat for trash mobs, full turn based combat for bosses. In general, neither requires strategy, and like a lot of these games it feels like filler. The overworld maps are large, but you can travel them quickly and there's not a punishing amount of travel or backtracking. Occasionally it isn't very clear where exactly the next quest objective is, but the answer is near always "the place you haven't been to yet" so simple forward momentum will carry you along.
H-content: As the player you push Ulrica from point to point on her quest to break her curse and at every stop something erotic occurs before she can continue. Things slow down in the towns where you interact with NPCs successively to generate a series of escalating events. Player choice is pretty non-existent. You enter the scenario, and the scene occurs, there's only one choice for h-content I recall and the choice was "mouth" or "pussy." Regrettably, there's very little dynamic interaction with the NPCs, usually the strong point of RPG maker games. Nearly every 'on the street' NPC delivers the same dialog throughout the game, irrespective of your outlandish outfits or experience. There is a very nice recollection room that gives good directions towards unlocking scenes, it's top notch.
Other considerations: I might have taken a star or two off for the linear gameplay, the generic filler combat, or the under-detailed art, but I feel the game is already underrated so I won't. The other current review by RedRob suggests the final boss fight significantly detracts from the game. I read his review prior to playing and was expecting the worst. Prior to the fight you're given an upgrade that makes all your previous leveling and equipment unimportant. Shortly into the fight the boss scrambles your new high level spells and renames them all ??? The good news is that this isn't a problem at all because you can always find your full heal reliably, it's the one you can cast on yourself. In RPG maker games, the first button press selects the skill, the second selects the target. Heal 2 in this game will always target the player. Even if you don't want to try guessing which elemental spell is which, you can wait out the ??? phase with heals and guards. Not knowing this fight is coming up or knowing RPG maker game mechanics could make this fight very challenging. Personally, I found the puzzle room in the succubus tower much more challenging. I can see where some players might get frustrated, but if you examine every object you are given all the information you need to solve the door code.
Final: If you're looking for ENF and mild corruption, this is a short enjoyable game with a happy ending.
