"Saimin App de Kanojo ni Kanochi" is a thought-provoking and emotionally charged game that explores the complexities of the human mind. While it may have some pacing and gameplay limitations, the game's unique concept, engaging story, and high-quality art and audio make it a worthwhile experience for fans of visual novels and psychological dramas.

Regarding the RJ01070770 free version, I was unable to find specific information on a free version of the game with this exact title. It's possible that this is a fan-made or modified version of the game, or it may be a mistaken or incorrect title.

If you're interested in playing the game, I recommend checking out official release channels or reviews to ensure you're getting a legitimate and safe copy.
