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 feel could be improved is more player feedback, this would help give clarity to who has more accuracy. This would be done with something simple, such as a bigger flash or different colours for the different timings the players can get.
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.
