Thanks for sharing your gameplay! It was insightful. I think there’s a bug with the E button where instead of teleporting you to the next zone you reset so that got to be fix :(
As for the last puzzle, you were actually supposed to die over and over again on the pedestal and use your dead bodies to open the gate. There’s actually a note in the area beside the first puzzle area that hints at that. I think more work certainly needs to be done on the game part to communicate as to what to do in each area
Thanks for trying it out~
