Go Mecha Ball

You will save yourself a lot of heartache and time if you make sure you UNLOCK UPGRADES ONLY until you have beaten all the difficulties. Beat the game with each character you unlock until you get all of those cheevs, then I recommend the third character or the one with the combat medic perk by default.
On lower difficulties you can use the purple quarter pipes and orange jump pads to safely land on enemies 2-3 times and then use a dash and finish them off with a gun. If you're really having trouble surviving and don't have many upgrades unlocked yet use the combat medic pilot. Once you've unlocked every difficulty, you'll be raking in the glitch coins and it'll be easier to unlock all the weapons and abilities.
There are a couple of great combos you can run with the third pilot, just keep trying and banking glitch coins until you roll a survivable perk set.
Look for:
-Cooldown and + Ability with dash and the bounce skill (in the pool from the beginning) you can dash and then bounce in quick succession and you'll be very hard to damage while stunning enemies and kicking butt
- Gun damage +, missiles on gun damage, guns can stun, and the turrets
a little harder deck to build but these can really spit crazy damage and stunlock most enemies

Adds metallic enemies (must be dashed to allow gun damage)
