“Honestly, I'd recommend any Spike Chunsoft game. They've got pretty darn good puzzles in some and the AI series has given me at least 2 great twisty murder mysteries (No Sleep hasn't been played by moi yet). Buy it or…”

“Overall a nice sequel to the first game. The story is less mind-blowing and more streamlined than in the first game but still has some nice twists to it. The new characters are great, especially Tama. I was happy to see…”

“cool experience, animations/voice line took a uptick which is nice, story's intriguing to an extent still highly prefer the first game in all honesty, not a bad expansion on a branch of the universe tho.”

“Better in every way to the 1st one IMO (I think this is an unpopular take). I like switch between the two teams. More of the 1st game but better. Still good characters, good writing, good humor and nice dub.”

“I wish there was a mixed rating for games like this. I loved the original AITSF, and I came into this enjoying the game a lot. I definitely missed Date as the protagonist, Ryuki and Mizuki are fine protagonists but they…”

“I so badly wanted to like this game. The first game seemed like a good return to form for Uchikoshi. But this sequel just fails on every level. Getting the elephant in the room out of the way, the political preaching.…”

“Ok it's HARD to recommend. This is the potential man of Uchikoshi games. So many interesting characters! What an interesting story and plot twist and major mystery! The somnia and gameplay are actually way better this…”

— a player, Steam review · 94 hrs played“As someone who loves the first game, I think this game is still good but makes a number of missteps that prevent it from reaching the same heights. Most of my complaints lie with the story despite it being more ambitious than the original. Mainly, the conflicts felt less…”
