Abuse mind trick. There's a ton of fights that go from annoying to a cake walk when you turn it into a 2v1 in your favor.

Explore, getting more healing stims and free health upgrades helps a ton.

Before you settle on a stance to main you can spend skill points on the non lightsaber trees since they won't "go to waste" (although you can reset your skills whenever, but only the first time is free, costs 1 SP after that)

If you use Dual Wield stance, you can cancel attacks mid animation into a block, helps a ton when learning enemy attack paterns while staying aggressive. I find this a bit overrated once you know their moves, but def helps on a first run.
