i've had an account on itch for quite a while (at least two years?) and yet this is the first time i've commented on a game.
i played through the whole thing (all endings and all possible species, though not all genders) in two days, and i enjoyed almost every minute of it. the pacing was just right, the tension, ash's inner monologue... the only things i regret are the order in which i played the routes, and that i didn't do my usual visual novel practice of aiming for the bad endings first, and those are both my own fault. the latter is a testament to how much i was enjoying it, though - i didn't want the bad endings. but, alas, i am a completionist.
i also had waaaay to much fun with the customization options. i don't know how other people play, but i had a distinctly different appearance for each "ash" - my first "ash" was a shika with the medium skintone, black hair, and brown eyes; cubi!ash had the darker skintone, pink hair, and blue eyes; and reaver!ash had the pale skintone, silver hair, and red eyes. part of it for me, i think, is that i have brainweird and having that stark of a visible difference between them helps me remember which "ash" i'm playing as. but i'm also just a sucker for character customizers.
i played paris's route last. (i should have just played them in top-to-bottom order from the selection screen! dangit, past me!) but my first playthrough was shika!ash, so paris wasn't an option then and i have so many regreeeets. i loved that there were different endings for braums's route depending on what species you chose (and i love that reaver!ash is a snobby little shit sometimes), and that there are little interactions with everyone that change depending on which "ash" you're playing. i'm definitely a detail person, and stopping my skip-throughs as a different species to see how the dialogue had changed was always fun.
my personal favorite route was rafael's. it was the first route i played, so naturally it'll have that special place, but i think it'd still be my favorite regardless. i found it interesting how ash interacted with a love interest of their own species versus one of a different species, as well - for example, i liked rafael's route better overall when playing as shika!ash (i found the shared cultural moments really touching, because it was something neither of them had ever really had someone to share it with), but i really liked playing paris's with reaver!ash (perhaps because reaver!ash comes with considerably more snark - not that ash is ever lacking in the snark department).
overall - i dunno, it was okay, i guess. pfff, i sure hope you can tell i loved it. i might even wipe my save and replay it sometime. need to wait for the emotional scars from my last run to heal first, though. god and in the good end! you know! [spoiler] wouldn't have [spoiler]ed ash! so that [spoiler] wasn't even necessary!!! why'd you have to do that to me that hurted.
