I vaguely remember hearing about this being on Kickstarter years ago but didn't think much of it until I happened to run across some screenshots of it the other day. I ended up watching some Youtube videos, and for the first time in over three years, paid for a video game by getting a copy from GoG.
I've been extremely impressed with it so far (I'm about 75% through, I think). I liked the GBA Igavanias but struggled to get through the DS ones due to how repetetive they felt; The "seal" mechanic from Dawn of Sorrow and the dual player crap from Portrait of Ruin just felt like gimmicks rather than innovation to me, and while I like the atmosphere in Order of Ecclessia the Glyph system and combat in general felt clunky and unrefined.
Somehow they managed to make something that feels like a true sequel to Symphony of The Night with this one (It practically is, just with the Konami serial numbers filed off). However, they also managed to take all the best bits from the portable games and incorporate them, as well as improve them, in ways that feel both natural and fun.
Overall it feels like a fusion of Symphony of the Night's RPG elements with Aria of Sorrow's Soul system and Dawn of Sorrow's combat. It also has some crafting type stuff if you're in to that, but it can be mostly ignored unless you're trying to get powerful gear earlier than you can typically find it via exploration.
The soundtrack is also exceptional, which isn't all that surprising considering the composer was Michiru Yamane, who also did Symphony of The Night's score.
I'm not overly found of the cell shading for entity models: It sort of clashes with the more realistic graphics style of the environments, but it's a minor thing. The NPC models could have also been done a little better, but Miriam's design is fairly good. There's also portraits all over the castle with seriously bad looking and immersion breaking images of what I assume are backers from Kickstarter. Fortunately a bunch of mods have already sprung up for the game, one being replacements of these with artwork by Ayami Kojima.
Highly worth the $30 I paid for it. I typically don't care enough about video games at this point in my life to bother making a post like this but I felt, in this case, it's a somewhat exceptional game.
