Hi, thank you for your participation! I have played your game but I have a few questions because it seems I did not understand it well.
What does the big white door do? When I entered it 5 times I finished the game. Every time I entered it some of the green pickups disappeared. Also, I couldn’t unlock any special ability until I entered the door for the first time. I also got stuck in a puzzle, see the screenshot. It was impossible for me to leave this area.
