I really liked this level! You said you made it during a stream? Pretty cool my dude. I did have one complaint:

I couldn't figure out how to beat it with both cubes, I ended up securing a portal on the eventual launch point and grabbing the laser cube from the other room, with which I used on the button to fall. I don't know if it's an exploit or if it was simply misdirection. Not such a bad level doe.
