The atmosphere of the game is really well done — the foggy world and especially the music selection create a strong emotional impact. Even though it is short, it delivers its message clearly and feels quite touching. The idea of progressing through memories and fragments of conversations is also very effective.
The only downside I experienced is that the game tends to lag when played in the browser, which affects the overall smoothness a bit. However, despite that, the atmosphere and emotional tone remain very strong.
Overall, if the performance gets a bit more optimized, this could become an even more powerful experience but even now, it is already quite memorable and moving.
