for #5 you're supposed to use the wood planks to hit the pressure plate, I'm shocked you can push the cube a bit to make it fit but it's definitely not intended to be used like that.
Jajajajajajaja, bro i was playing, and i tried to do the cube thing before watching the video, and i thought "it just barely fits this is hard" but i did it, then i watch the video because i was curious if there was other easier way then they did the same as me. Then I played again i see the wooden planks i and thought "well I could use a soda can... But I need to move the wood so i already lost, has to be the cube" and then i read your comment xD
The challenge mode is like the base game. Very cool beginning to very boring ending. The first 2 or 3 levels are pretty challenging and then there's nothing special about it anymore. I liked how I had to rotate the cube so that the cube reaches the button. There's nothing like that later in the game.
@@Katz3nFr3und you're absolutely right, the game started off so strong and amazing but as you get deeper in the game the puzzles fall off and just starts to just become a perception bending visual experience rather than a true portal-inspired game liked I hoped it be. Cool game anyway but they really should have stuck to the more test lab level design and expanded on the amazing base mechanics. They could have done so much more with the size altering, the duplication, and the way some objects get turned into a flat texture on surface of everything behind it.
