Nice take on an old classic :), maybe you could've included a screen that tells you if you failed or not, and some bg music.

game goes black after a few rounds and stays that way even after refreshing the browser please try and fix the glitch. thank you!

Basically it's Space Invaders with better graphics. Nothing terrible, but I feel the game is a little slow.

After a few gaudy rounds of Space Invaders, the game just stops on a black screen.
