I got stuck in the first gate and i would not proceed to the next stage.

I liked it. After you learn the basic strategies it's kind of easy though.

Also, when I was on lvl 30 suddenly my cannon wouldn't break bricks anymore (after breaking a few). Then, I restarted a bunch of times to no effect, so I had to give up. Fix the glitch! =)

I liked the game, though there are some points of attention.
For one its slightly laggy and buttons dont always work.
Also dont put a shootable enemy behind clickable buttons.
