Backrooms level 1

Level 1 "Habitable zone" is made up of three parts where it all ends at an entrace to Level 2. I really recommend playing Backrooms level 0 before this challange. The challange contains some flashing lights but only for brief periods of time, it also contains effects like fog, so i recommend putting graphics to a maximum. It can take a minimum of 3 minutes to finish each part of the challange if you try (except part 3 is shorter because it kinda sucks tbh), but if you are playing for the first time it can take up to 10-15 minutes to finish the whole challange. If there are any problems just comment. Special thanks to ScrapMan for continuing the series. I really hope you enjoy the challange my dear friends ;)
