I loved the game but although most people say the survival is really the hardest part i found it easy(lucky dodges maybe?) and the arena took me several hours of trying(literally)to beat it. I played the game on sower computer and had youtube running in another tab and run into some issues sometimes the controls froze and no matter what I pressed the game didnt do anything resulting me in taking damage at other times my character run straight right or left and I could not stop him. Another thing that annoyed me was the black captain when he knocked me back I couldnt do anything to stop and resulted in taking more damage. The next thing that I didnt like was the captains upward strike (because I suck ;) ) it was nearly imposable to not get hit by unless I got lucky and It also hit me when I was standing on the rocks "spawned" by the engineer. Otherwise I dont regret using those hours to get the imposable badge :).
Thank you for reading it all and the amazing game.
