The short format is really a good idea. The pixel art choice also !! It reduces the "trauma" of blood and give the game a cool style.
It can be pretty strange to play and I wanted to avoid any surgery but seems impossible to access to the next step in the story without a minimum of surgery (2 main surgery ?).
Played it twice. And seems to have also at least 1 or 2 other endings.
I pretty like the way we can understand the character background, according to the ending we got... Each time it ends "the same way" but the guy is enough enigmatic to make it work and make us interpret different things.
