Hey there :)! I appreciate you trying out the game! I severely underestimated this project and the time it would take, but has helped me to learn to make the objectives more clear in the next project!
As for what to do.. Each time you go through the doors something will change (sometimes the direction you enter will affect the outcome as well :) ), leading you to further progression. The game is supposed to feel like you're in a purgatory of sorts. I was so crunched trying to get the puzzle working that I realized I hadn't quite explained what the heck to do / expect!
