This game has a fun and engaging gameplay loop, constantly testing the player's skill and reaction time. Because of these skill factors, the game has a very high skill ceiling despite its simplicity with a high score system used to incentivise players to come back to the game.
One area of the game that I do feel is lacking is the graphics, while it is simple and allows the player to focus, it seems almost too simple and rushed. While it's not a necessary improvement to make the game more fun, it will definitely help the game feel more polished and complete, it can also help with player feedback and engagement.
Along with this, I noticed that the game only shows your high score after you have died, I feel like it would be a great addition to have your high score while playing along with it being on the main menu, this way the player will always have a new goal to strive for which may help with player retention.
