Well if you wanted to convey the feeling of loneliness you did it. I mean it should be just a simple match 5 style of game but the quiet whispering aesthetic and how instead of swapping places you erase letter makes a unique experience. Good job!
Not a critique but I'm wondered if you had considered a sliding mechanic instead of an erasing one. I think the idea of the other letters "running away" from you may more align with the lonely aspect. However sliding puzzles exist so the erasing mechanic is more original so. *shrug*
