It's working! Neat little game. :) Tough but quite addictive.
Just one observation so far:
The dark blue text on a predominantly dark grey background can be bit difficult to read. Suggest using a contrast checker website such as WebAIM to ensure that your text colour is readable, especially to people with visual challenges. You should be looking at a contrast value of 4.5 or above.
EDIT: A rough estimate of your colours gives a ratio of 1.8:1
