namang19's review of Getting Over It with Bennett Foddy.
My first run took me 10 whole hours over several stressful yet oddly fun weeks. 15 mins after finishing it i started playing it again and then beat it in 40 mins.
You think you'll get this immense feeling of satisfaction and victory to be surprised by not feeling all that you thought you would. It is then that you realise it was never about getting to the top. It was just about playing the game.
