Okay- while I find everything else in this level pack as fine enough for the scope you're going for, I have one, massive, major complaint.
Electric Base's boss is not fun. It is not player-friendly. And god is it a visual pain.
First of all, do not use that pulsing floor type THAT much, in a room with that brightness. It's a huge pain on the eyes and I had to squint in order to bear through it.
Second, the texture you used for it is often used for damaging floors. This floor does NOT damage you, and I had no awareness of that. I spent about ten of my attempts thinking I had too little room to move, when I finally landed on the floor and realized it wasn't consistently hurting me.
Third; I did not understand why I was randomly being hurt on the pulsing floor until I realized what you were trying to go for, and with how the texture never changed, I never knew when he was going to shock the floor and simply jumped, hoping for the best.
Fourth; when the boss DID shock the floor, he often either launched a sphere of electricity at me, which was fine, or he sent out a circle of electricity at either floor level, or his height, which was an issue as you can only hurt the boss for a second or two after he attacks, meaning the best chance I have to hit him when he does the wave is either pray the circle of electricity comes out at floor level so I can jump over it, and hit him in one swoop, or stay far away and hope he doesn't do the shock-ball attack since I can't reach him, while also staying on the floor on a corner and having to rush to make it there with no visual indicator of when the electric floor stops being painful, while making it under the shock-wave if he's at jump-height, and THEN jumping.
This boss is so sporadic and it feels so unfinished compared to the first boss, and I think you need to rethink it's mechanics- conceptually it works, but the way you executed it is, not to discourage you, horrible and unfun from what I played. It not only needs better consistancy, but better visual identification for attacks and danger is a must, as well as making the entire floor not repeatedly blast me with a rave party where the sun's the rave-lights.
