You have a good tutorial, but so long that when I was finally ready to play, I had lost my wish to play... You should REALLY add a controls description in the instruction section outside the game.
I was thinking about your game, and I think that if you make the changing gravity view flip at the same speed as when we press "Q", you'll greately reduce the nausea effect, and it will be easyer for the player to figure out and calculate the momentum and the aiming vs the view.
Help me please. I don't know why but I can't use the keyboard and the mouse at the same time. I can only use the keyboard, and when I finally press ESC. to exit the screen, I'm in control of the mouse in the game. So I click again in the game screen to play and suddenly, I can again only use the Keyboard and not the mouse...
