Thanks, buddy! Merry Christmas to you!

Also Merry Christmas 🎄

Portal 4 🤣😂

Oh ok. Yeah, I say if you can pull that off then you get extra points for making it harder! LOL Thanks!

Basically in Helium Cubes there's a very tight window of frames in which you can shoot a portal on the flipping panel without using sv_cheats. If you gently nudge a cube out of the way of the laser you can manage to shoot portal onto the panel just as the emancipation grill starts to form. It's not puzzle-breaking by any means, it's just as intended with a slightly tighter step. Very cool chamber, again.
