AI2U: With You 'Til The End

You wake up in the home of a cute girl who's eager to keep you by her side! Engage with thematic stories, puzzles, and yandere AI NPCs who'll go to any lengths to protect you—even if it means contradicting themselves. Bask in sweet meet-cutes, or brace for chaos if you dare to escape.

In short, Steam reviewers most often praise “Dynamic AI interactions” (65 of 103 reviews) and “Multiple endings and outcomes” (12); the most common complaint is “AI dialogue and logic failures” (24). What reviewers agree on ↓

“This game is fun, but maybe not for the reason the devs intended. It's much more enjoyable to just say the most outrageous, stupid stuff to the AI NPCs to try to get funny reactions, rather than actually trying to progress the game or solve the 'puzzles.' Speaking of which, the…”
