Ehy Thomas, this is fun! Really like the atmosphere and the story but I couldn't progress too much, I'm stuck in the meme cemetery, is to hard to move the player and fight at the same time, I mean the key binding + mouse to fight it is kind hard... Don't know if other people are comfortable with that, maybe if there is a way to avoid using the mouse...   

Yes.

Make 'a' 'w' 'd' as left, jump and right.

This is my only issue with the game, but it's such a huge, gamebreaking issue. They're so unnatural to use.

I personally think that controls are fine, definitely not gamebreaking. Every fps game has controls like this, W-A-S-D move, Space jump and Mouse for attacking and aiming, nothing hard to control.  You also need to take in consideration that its made in only 14 days and that Thomas made it only because PewDiePie dared him to make it, i don' t think he will work on this game anymore since there is nothing to work on anymore, he will probably focus on finishing once a upon a coma now.
