No matter which ship you own, upgrade its boost over and over again in order to make it better against the enemy forces. If you are looking for a high score game do not warp. It simple really, the more sectors you go through, the more points you will get, so Warping will only reduce your potential top score. Watch ads to continue when you are in a good run. Try not to spend your hard earned gold for this. Learn the patterns of the enemies. IA is not that hard so make an effort and use it to your advantage. Same can be said for boss fights. Best to stay as far away from the boss as possible so you can easily squeeze through bullets. Bosses also follow a pattern so learn it as well.
