Thanks. Btw, what part of the level you got stuck on? Was it because of the button placement, fire boxes (or torches), or Was it the timing? 🤔
So if you already have noticed the fire boxes light up when you press the top button. You can use the fire boxes to reset fireball's "ticks" I'll call it to 2 when it touches the lit up fire.
So you shoot a fireball a tile before the buttons, the fireball is able to bypass the switch blocks below since the button isn't pressing pressed. As soon as the fireball is up there, step on the bottom button up until the fireball reaches the the top floor. While it's up there, quickly lit the fire and stay on the bottom button up until the fireball passes the wall. After that, to get the switch, step on the button again and for the generator don't.
I know that was a lot, but that's my fault on my end for thinking this level was a bit to easy when my brother beat it in at least 4 tries.
