Luwis 2D Airplane duel

A two player 2D game, where you steer your airplane by solely by accelerating or not. Collect coins and shoot your opponent to earn points. A coin is worth 1 point and being shoot or colliding with the ground gives 5 points to your opponent. Player one keys: "Q" and "W". Player two keys: "I" and "O". Restart with spacebar. Unfortunately I have not been able to adjust the text fonts and placements depending on screen resolution, so some things might look bad.
