It was a great visual novel overall! You hit that mysterious element perfectly. At the same time, I found the characters rather charming and cute. Everything blended well together here; the artwork and music choice complimented the story wonderfully.
I always enjoy trying to see all of the endings in games like this, and a lot of them here were quite interesting although somewhat painful (emotionally speaking) at times. However, this only emphasizes how good the writing for the characters was; despite being shadowy blobs, they all possess their unique personalities, and it was easy to grow attached to them, even given the short length of the game.
Fantastic work overall, and I’m glad I got to experience your game!
Linked above is a video I made of my time with the game.
Cheers and take care!
