What a fantastic title. After 40 or so hours on this, I just had to share some of my thoughts.
As someone who hasn't played 1-4, but saw all the attention this game was getting, I was relieved to see this was a reboot (story-wise, at least). I knew of the other games, but never tried them. Everything in the game here was explained well enough, whether that's game mechanics, the plot, the world, etc. that I never felt like I needed to play the previous titles to understand what was happening.
One of the places this game absolutely hits it out of the park is in the gameplay. Exploring the world had a point-and-click/I-spy sort of quality that was a blast, and really encouraged me as a player to keep my eye out and soak in the environment. That aspect of the game always felt rewarding, and even after 40 hours, I feel like there's still a decent chunk to see.
The meat and potatoes of the game, though, is in the combat. Between summons, equipment, skills, swapping out characters, and more, there was plenty of depth, with all elements layering together in a way that frequently rewarded experimentation. There are so many details of the combat that work great, it would take me ages to list everything out. The difficulty was exceptionally finely-tuned, too; the only time I felt overly challenged was with the final boss, and maybe a few other bosses here and there.
When it comes to the art, you've been making the best I've ever seen in Vector-based games for years now, and this is the crowning jewel. There's so much love and detail packed into the characters, environments, and items, the effort that went into this is plain as day. The environmental art is my favorite part - even though it was packed with detail, it never felt overwhelming, with ample space given where it was needed. It always tied back into the gameplay perfectly, making it clear which elements were meant to be interacted with, and what was just eye candy. Fantastic use of color, too! The only criticism I can give here is that the animation was a little too tween-y for my tastes, but I feel like the game's inspiration from anime, which typically does favor a detailed still image over fluidity of the animation itself, is where that was drawn from. Being a turn-based RPG, I think a focus on how the character's look standing still rather than in motion was a wise choice.
Speaking of visuals, the UI worked pretty well too. Clean, easy to understand, use, good font choices, and easy to compare weapons. I would've liked having stats and equipment in the same window, though.
The music and SFX were good too - Phyrnna did a good job with the score. I don't have too much else to say about the SFX; they were high-quality, and always fit the scenario/character they were being used for. Kudos!
Regarding criticisms, I didn't care much for the story, characterization, or humor. They leaned very heavily into anime tropes, which I'm not a fan of. I did like the final boss acknowledging the nature of sequels and this game's nature as a reboot, though. Speaking of the final boss, I was surprised to see such awful, low-res photos used for the space scenes when the rest of the game has such lovingly-made and highly-detailed art; it felt like there was a deadline that snuck up on you here, and you had to slap something in there. For the final boss, I also would've liked having the two phases split into two different encounters. I found the second part very difficult, so I would've loved being able to go right to that every time I restarted, instead of plodding through the first, much-easier part every time. Also, a fast-forward button during combat would've been nice. The attack animations were fine, but after a certain amount of time, you want to just make your combat choices, instantly see how they play out, then make your next choice.
All in all, it's bittersweet to see such a huge, ambitious, lovingly-crafted game like this likely be the last hurrah for Flash. This is one of the biggest games I've ever seen on this site, and you should be proud. Glad to see it getting some love on Steam!
