Yeah, the games I make in Construct 2 seem to work best with chrome. I made a simple physics-based game and posted it to a forum and one guy said it ran so slow it wouldn't hardly do anything.
I think I'll speed up the ship a considerable amount and cut down the playing field a bit to speed up the action. I also plan to add asteroids to shoot to keep the game interesting once you destroy all of the enemy-spawning bases. I also plan to add power-ups, bonuses, and levels that consist of space invaders instead of the bricks.
I allowed the player to shoot the ball to help speed up the game when there are only a couple blocks left and sometimes it would get stuck bouncing completely horizontal. I'll probably have to use some special actions to get the bounce right instead of using the built-in bullet feature.
Thanks for the feedback, everyone!
