Description

this.particles.update(dt) is called in two places each frame:

Inside _loop() at line 250 (variable dt, outside fixed timestep loop)
Inside _update() at line 273, which is called inside the fixed timestep loop (line 248)

Impact

Particle positions are advanced twice as fast as intended. Exhaust effects and visual particles will appear sped up or jittery.

Fix

Remove the this.particles.update(dt) call at line 250 in _loop() since _updateParticles() inside _update() already handles it within the fixed timestep.
