User Reviews

Users praise the game’s art, visuals, and engaging plot and characters, highlighting strong artwork and appealing romance. However, the majority report severe stability issues: frequent crashes on startup or during loading, making the game unplayable. Recurrent data/persistence problems are also mentioned—iCloud saves not working and purchases/progress not restoring after reinstall due to a missing restore purchases option. Overall, the app shows high potential but requires urgent fixes to stability and reliable data restoration to satisfy players.
Pros
  • Beautiful art style and character designs
  • Captivating plotline and romance
  • Well-developed characters and relationships
  • High-quality visuals and overall aesthetic (CGs)
Cons
  • Frequent crashes and exits, often preventing gameplay
  • Data persistence issues: iCloud save not working and progress/purchases not restored
  • Missing or non-functional restore purchases option
Recent reviews
I recently redownloaded this game after several years of not playing it/having issues getting it to work on my new phone due to a glitch, and none of my past purchases or game data have been saved (even though the beginning message states that game data and items will be automatically saved into your iCloud connected to this account). I can’t find any restore purchases option either, so for the time being, I can’t recommend playing this game or making any purchases in it to anyone until the issue’s resolved. (Otherwise, the art and storylines are cute. The translations were a bit wonky at times though, based on what I remember from last playing it several years ago.)

I can’t put more stars when I can’t even play the game it completely exits out of the game not even letting me play at all

The app keeps crashing a lot. Like, A LOT. I couldn’t even start playing because it didn’t let me get past the first few loading panels.
