The game itself is difficult but the game is so short that the lot of deaths happen in just an instant, which makes it quite light to practice doing it quickly, apart from that, the fact that there are multiple endings motivates you to explore it a bit and see how you can improve. (or get worse) in multiple games as you get familiar with the levels or start to feel like your fingers start to hurt from the precision you occupy and the high number of times one has to use the jump button.
An interesting theme in the game is that all the endings where one seeks to further extend one's existence feel like bad endings, the protagonist has long since passed his natural life with an artificial heart and every scenario where one survives is full of regret and desire. to reach the end. Only when the end of life is accepted is when one is freed from regrets and can rest in peace with the time he has had to live, whether it is saving a young woman who has her life ahead of her or simply stop running and admiring the beautiful night sky for the last time.
Definitely a good game.
