I REALLY enjoyed this game, the level of polish is very impressive for a one-person fangame, everything felt really well-made on every level, the use of colored text, the presence of difficulty options upon failing minigames or the possibility of skipping them entirely, the simple yet clean level-design makes it so that you never feel lost, the variety in gameplay is quite creative and some of these sequences were very strong points of the game in my opinion (as for the infiltration sequence someone commented on below, I personnally found it fine as the screen is clear most of the time, but I think it could maybe be one section shorter). The polish makes the game very pleasing to play through, and battles never feel like a chore, which is a balance I find pretty hard to strike in RPG maker games. Also I can't believe you translated the entirety of this game's text, including some puns, in another language, that is a ridiculous amount of effort.
The battle system is very original, and it makes you have to think even through random encounters, which I thought was cool, and makes you weigh your options every time, particularly the manipulation of turn order through multi-hit attacks was a lot of fun. The story was neat, and I thought, thematically appropriate for Hololive, and the universe and dialogue were vere very fun and full of references that never feel shoehorned in to the detrimend of the overall story, to the point that I think even someone wholly unfamiliar with Hololive. Everyone having a more-or-less fitting role for their character and mostly appropriate dialogue (which is obviously hard to do with so many characters) was a great touch. The dialogue was fun without being too wordy (I loved the underwater part as well, very creative).
The art is very cute as well, did not expect every Hololive member to be hand-drawn or even some full pieces but it fits with the attention to detail that characterizes the whole game (like the seemingly innocuous presence of normies in every single town that you don't really notice until it becomes relevant, or everyone having new lines at the Inn every time). I definitely did not expect a fangame to be either this long (I personnaly clocked out around 6 and a half hours), or this well-made, and I felt like the amount of effort and love you put into this deserved at least an in-depth review. As a result, the only complaints I would have are very small and subjective, which is that some dungeons and infiltration sequences feel very slightly too long, and that I wish more background elements were interacteable (which I definitely understand requires a lot of work and is just a minor thought). I don't know if there is some kind of payoff for finding ninja Sora I missed, but if there isn't, I think having one would be cool ! I see below you currently don't have any plans for a part 2, which I thought the end was hinting towards, but I can only hope you can find time for it at some point (maybe with some Holostars and staff members added to the mix with the most recent members ?). Either way thank you for making this game ! I might have forgotten some things I wanted to comment on since the game is so rich, so if you are looking for feedback on anything please feel free to ask me !
P.S : Out of curiosity, what are your favorite jokes/references/sequences in the game ?
