Pretty fun game! Its a nice concept with the movement you got + the boost from breaking a certain amount of walls. Music fits nicely and art + glow effect is good.
One thing to note is that when you speeding up from going slow, breaking walls can be extremely inconsistent. Sometimes I can just click to fire, go into a wall and it breaks, other times it just does nothing.
Another thing is the main premise of the game can be circumvented by just spam clicking at the start. Firing your gun twice before hitting a wall gives you a massive speed boost that you can then capitalize on to mass break walls by spam clicking.
