I unfortunately couldn't get past the first puzzle. I walked around and sometimes clicking on the character shot energy beams onto the nearby circles, but then nothing. I'm on the Mac jam version.

The puzzles are quite challenging and require some pretty big leaps sometimes. The first puzzle requires you to use the first symbol to move the sphere from the bottom to the top, you then need to use another symbol to power the sphere once it's at the top, then use the final symbol on the door to open it. We could have done with some more hints in hindsight 😅
