I've always been a big Kogasa believer (kinda expected her to be in 14.5 tbh) and it is a pretty nice surprise for me to see her in this here game, especially with danmaku that make obvious what they're supposed to be.
Anyway, Tasofro fighting games plot had this little thing where they could afford to not only tell the story from the point of view of the baddies behind whatever incident, but also from the point of view of various miscellaneous characters as well. I hope this game is gonna have more than just Reimu as a playable character in light of that. I can see this game potentially being a point of entry for new fans cuz platformer. I hope Tasofro made a good job in introducing everybody to this game's mechanics and that there isn't going to be some sort of super important but hidden and not-necessarily-intuitive mechanism.
There seems to be stuff like spellcards, so I'm gonna assume we might potentially have stuff like spells breaking ? While I've seen lots of people mention the success of Touhou Luna Nights as an inspiration of sorts for this game, I'm kinda expecting it to take after Tenjou no Tempest tbh.
Regarding the artstyle, personally, I'm a bigger fan of the sprites from the new gen fighting games. A screenshot is just a screenshot and is completely immobile : I'm looking forward to see how the animation for the new sprites is gonna be.
And I hope we're still gonna get some character portraits for this one (especially for Tout- er, whichever newhu we're gonna get), cuz that Reimu-Marisa scene doesn't seem to have one ?! Hopefully it's just the case of screenshots not showing everything.
And finally, since it's pretty much expected that this game's gonna have some kind of water related gimmick, I'd love to see a bunch of familiar faces that are able to interact with water to a certain extent make a comeback : Wakasagihime, Murasa and Cirno would be pretty cool, but I'll have you agree that a Sanae that walks on water, turn it into something else and even split it would be pretty darn dope
. Personally, I'm REALLY expecting Nitori to be in this game, cuz the part about people seeing some kind of financial opportunity in this crisis simply have to come from people with a reaaaaally Kappatalist mindset.
Anyway, I would love to be surprised in a pleasant manner. Freshness is something that this series really need, but there is always a risk associated with trying something (relatively) new. I hope this new game is gonna work out.
