The game has plenty of bugs. The minimalist art style is fitting. The sounds are okay, but music is missing. The gameplay basically works, but I would find it more interesting if the walls were arranged in a more complex way and didn't break so quickly, because then you could use them more tactically. I wish I could attack 360° with the mouse, but maybe they deliberately decided against it. With the walls in question, it would fit better to be so limited in shooting.
The bit about the bugs was a pun, by the way.
