How you can finish Trial of Air easily: 1. Upgrade the passive upgrades speed of light, mercy, shieldify, second chance, regeneration, deflector, power up, and rebound to the max. 2. Upgrade and use the active upgrades walker, forcefield, athleticism, invulnerability, and invincibility shield. you can get a headstart in the beginning by dashing in the spawnpoint area towards the chainsaw thingies, then use your Q (Invincibility Shield) in the bullet hell parts. when you're low, you can regen your hearts if needed. :)
