Well, it looks good so my score is giving you the benefit of the doubt, but i've encountered a glitch at the map screen, apparently there's meant to be a shop there but all i see is asteroids. i can see my credits in the top left and i can access the menu, but other then that there's nothing. I can't continue the game. i've tried re loading and i'm playing on chrome.
also, a side note, the game doesn't fit into my screen properly. could you make it have an option to reduce the size?
