Thanks! Sorry to hear you struggling. You may've been unlucky and got a really difficuly level, as all the levels are randomly generated! If you play again you may have an easier time (you can also get a new seed by pressing "G").
A stratigic tip is that you can try to lure all the ships to one corner of the map by walking on the stations, and then going to another spot while they are distracted.
Also just to make sure I hope you didn't miss the information about how ships won't follow you to stations of other colors, this is the key to stop them from chasing you.
