Was past the point with the T blocks, then the game crashed.
Fun game! The controls feel nice and responsive, I like that it progressively gets harder. Though it has rage-game elements, they are easy going to make the ascent not too frustrating, like the ball falling down slowly, the V blocks even in high levels catching the ball safely and the horizontal velocity slowing down so the ball doesn't get out of control after missing a platform.
The sea sound is also soothing for the moments when the ball drops 6 platforms.
Sometimes the ball landed too close to the borders of the screen, which made aiming horizontal shots difficult. Also the game froze/crashed, it happened when the ball landed between the side of the screen and the left side of a V block. The sound stuttered and the chrome window froze.
This has a surprising amount of polish for being such a simple game, nice work!
