Hey, hey Quentin Delvallet! I'll tell you a secret. The electric boss level 1 (yes, there is another stronger version of it), is very vulnerable if you destroy the electric orb. Its dash is predictable and if you are distant, it cannot harm you with the falling attack. The alternative are air maneuvers with dash. Because the electric orbs always move and reflect at 45 degrees, it's relatively easy to predict where the straight line between it and the boss will be at.
With all the above said, this boss will be redesigned.
Thank you!
