After playing the game for the past few days I fell upon a few bugs, so I just went on and fixed them...
The line crossing routine had a bug, a vertical and a horizontal line would often be detected as crossing even if they didn't... FIXED !
Also fixed a stupid bug : when selecting a level from the menu, it would always return to level 1 :/...
On a minor note, I put the same font for the timer, looks better (or not)...
