So far it's solid. I can tell this will be a lot like Magical Girl Celesphonia.

Just started, finished the tutorial, and it's very involved with all the game mechanics, its kind of a lot to take in, to be honest. Lots of mechanics related to each element, and how they work together, dark slows and weakens enemies, and wind can only be used in certain situations... it's frankly a lot to take in. But the art is nice, the UI is so well designed, and the artwork is amazing.

It's likely going to be more involved with it's RPG mechanics than your average RPG maker Eroge game, so you might need to really try to understand the mechanics before you manage to accurately get into the flow of the game's mechanics. The story is corruption based, entirely. Your innocent Protagonist, for some reason, releases certain "Pheremones" and was raised in a very sheltered envrionment. It's heavily implied she was betrayed as well by her maid, and now finds herself on an island, left to her own devices as she tries to figure her way in the "real world" which is a night and day comparison to how she was raised. She's depresingly naive, and she will make you frusterated at her lack of real world experience and lack of wariness of men. As we all know, men are the worst, and must be avoided like a plague, especially if you value the "Pure" route, which is something I default to in all Eroge's in my first playthrough, as I want to see the actual gameplay choices availible in each of these eroge games, which are often confined heavily to the premise of it's genre.

Will update if needed, but if you like as mentioned in the beginning, M.G.C., this game will be a solid continuation from that game. It's not a sequel, but it sure feels like at least a prequel to that game as this takes place in the past, with goblins afoot, and other monsters.
