I didn't really play the game much as it runs far too fast. However...
1. The font-end is inconsistent. On the title screen I can press SPACE or LEFT MOUSE to continue to the front-end. Once there I can press only ENTER to select an option. If I choose High Scores then I can only press SPACE to get back to the main options screen.
2. The background on the game screen (as in your screenshot above) is very distracting. You need to dull it down a bit to make the foreground/important stuff more prominent.
But first and foremost you need to introduce some sort of timing to control the frame rate.
