Thank you for playing my game! Thank you for the helpful insight. The single pixel in the middle of the screen is supposed to be a simple crosshair. I did have issues with getting audio working, sorry for that. The game is not restarting it is supposed to be bring you back the start like the endless door hallway in PT, in hindsight I should have a fade on screen or better indication of it. The gate opens and closes every time you interact with it, which I forgot to remove. Each hint is for each loop. Sometime later this week I will be uploading a guided document or video.
Again Thank you for playing it and giving feed back.
