[v0.11]
Even with the game having obvious faults, this is the most enjoyable and interesting "standard" heroine-game I've played in a long time.
The setup of the game and the story is very standard, with the "pure" heroine being stranded in a "corrupted" and dangerous place while being pressured to do dirty things to survive. The writing or assets for the scenario are nothing out of the ordinary for this type of RPGM-game.
However, what the game absolutely nails is it's MC. The characterization for Eilayda is built on standard tropes, with her being haughty, naive, sheltered X000-year old fairy-girl, but the game does a distinctly good job of never making those qualities detrimental to her character. She isn't made too stupid naive, or arrogant to be in a nominal position of power (or walk and chew gum at the same time), and she reacts to the plot and other characters fairly realistically, having an internal dialogue of trying to understand their motives and moderate her response accordingly. The end result is that she feels like a likeable, believable protagonist. The bar is very low for good H-game heroines, and Eilayda clears it with meters to spare. Sometimes, that's a sign that the story is going to do something pretty brutal to the MC next, but I'm sort of hoping that isn't the case in the finished version...
The game does a decent job of having interesting gameplay-systems, with many custom minigames made within the limits of the RPGM-engine. It also makes an attempt at having an original character-building system, in having the heroine's mana be used as both "exp." and a combat-resource, while also limiting your healing. However... this might also be an example of why these systems might not be that great of an idea...
As much as I enjoy the heroine and the concept, I have to agree that the game is very grindy. The amount of content in the current version is still pretty low, and there is enough things to do for one daily cycle of minigames to do, as you slowly grind up more mana and daily gold to clear just the second dungeon. The game makes the choice to stricktly limit your healing to once-per day, with no repeatable healing-spell, and then designs the dungeons to have combat that is stricktly detrimental to you, that needs to be cleared over multiple runs through. In short, the grind is pretty annoying, and the slow-corruption doesn't have enough tools or events in yet to make it interesting. (Not that I dislike the the slow pacing of the corruption itself) And, of course, the current version lacks a major payoff for all the grind, and it will no doubt be more annoying the second time.
On the art-front the game isn't doing anything amazing, though the quality is still good overall. Only the main character having unique art, without particularly many frills like extra facial expressions. As I said before, the amount of scenes is currently kind of low, and besides the welcome hints of MC-sadism, there isn't anything particularly unique about them.
In short, the game is mostly held up by how much you like the MC, who's a pretty likeable character, especially for the archetype. It's unfortunate that the game doesn't seem to be heading toward breaking the mold of heroine games, but if you don't mind the sameyness with many games that have come before, this is a well-above average iteration.
