Hey thank you, I'm glad you liked it! :D
(spoilers for those who didn't see the movie)
Here's the thing: in the movie there's a space between the cube and outter shell to prevent people from simply reaching the exit. In order to get out, they need to find a room that will act as a bridge between the cube and outter shell (that room should have the coordinates of 27). This is not added in the game, the code does not support it yet. (technically I could hardcode it in some way but there would be no logic to it except being random on whether the room will be a bridge or not. The game wouldn't be beatable with 17,000 rooms)
(/spoilers)
I'll have to redo most of the project to make it work, but that will take a long time since I'm prioritizing other simpler projects. I hope you won't mind.
