Hail Discordia!
Don't worry, I play on a keyboard, and it's not that bad at all. keep in mind that your hitbox (collision area) is less than 1/2 of the ship's overall width, which should help navigating through bullet bursts. When you see a pattern you're afraid you won't survive, bomb. That should keep you going for a while.
Oh, and try not to take more than three of green and blue items each, otherwise the game becomes harder.
