What an interesting concept for a VN. I think what really elevated this was the fact that you didn't just use standard emoji but these cute ones that fit the rest of the art style. Also the fact that they don't just always appear the way regular text appears, but sometimes have special animations.
This was a cute little story and it was understandable without using any words. The art is so adorable :3
Oh, and the character's "voices" reminded me of lylat wars and undertale!
I checked out all three endings. Luckily, the last one I read was wholesome, so I ended it on a good note :)
