Hi! I haven't finished the demo yet, but I HAD to pause the game for just long enough to get my thoughts down to you. Right off the bat, as I played the intro, I was thinking 'oh, good graphics' - and I've been holding onto that opinion solidly so far. The graphics and the mapping are gorgeous - I really love how dedicated you are to conveying a setting's specific vibe or feel, with all the extra efforts put into making it more realistic. Your visions, I feel, really translated well in-game, especially with regards to the Temple in general. The stained glass behind the altar and the signs of ruin really resonated.
There are a few lines of German dialogue that I feel slipped through, but they're not at all detractive, considering that this is still only a demo. I really like the fact that we as the spirit have the ability to choose our personality in a sense, and am eager to see what the consequences of us influencing Shawn are. I would have liked to see a they/them option for the spirit, actually. I'm also not sure if this is a bug or if it's just my game, but after the Temple explodes and you go back up to find Aura, there's a section where you can climb up a cliff using the grappling hook; one of the animals there seems to be stuck with a tree, blocking the path to the little glowy thing (and I should say I really love the glowy thing. It's like a beacon, and saves a lot of trouble searching). There's also a little bit of lagging in the fights after Sarah joins, but I can't say if that's just my laptop.
I'm not too far into the game yet, but I hope I shall be able to come back and give you more thoughts once I've finished the demo.
EDIT: The demo has been beat, lmao. Spoilers for any new readers, but GOD, do I really, really want Raphael to survive. He's grown on me very much over time despite being a simpler character than most of the cast we've seen so far. Something about those big buff do gooders with their hearts of gold, you know? I'm also rather interested in whether that last kid - the one that joins your fight against Aziel, whose name I seem to have forgotten despite reading it a solid ten minutes ago - is going to join the party for real, but that's neither here nor there. I do think that in the game to come, I hope that our interactions with Shawn can be measured in a counter of sorts - it would make it a little easier to keep track of any spirit-related skill upgrades, or just gauge the relationship you have with him at any point in time. It would also be nice to have a counter to track Shawn's relationships with each party member, even if it's not necessarily romantic - I feel like his friendship with Raphael could be explored beautifully, haha. I'm a bit of a friendship buff when it comes to adventuring parties.
Also another obligatory love letter to the GRAPHICS... so gorgeous and so so so contributive to the atmosphere. The love and effort you put into the game is really fantastically visible. Thank you so much. I really can't wait for the full release.
