Thanks again <3 It’s really cool that you figured out the box is used to pass the traps I thought it would take a bit longer to solve and get through!
When the bug happens, you can press Escape, go back to the main menu, and rejoin the same level. I think what happened is that the cube got stuck between blocks. You’re supposed to use the box to test which block has a trap, then take the box back and place it on the button.
About the camera — it’s designed to show more details of the map and give a slightly cartoon-style feeling. :)
