I couldn't get past the first puzzle :(
The red cube can't be picked up, and it seems like that's necessary to open the door
Hello, thanks for the feedback.
that puzzle was designed to teach that you can bump the red cube with the other one to get it down.
I will work to make it more clear next time.
And yeah you can pick it up if you stand right next to the glass library just at the tip of the raycast.
Should have probably made the raycast longer.
