Likewise, you know I've been following the progress of this with much excitement, as I too consider CUBE to be one of my fav movies.
Happy to say that I'm not disappointed. You've managed to achieve a HECK of a lot in the time available. The game is gorgous already and sounds immersive too.
Obviously, it's unfinished and (unless u were born a mathematical genius) I agree, more boots would've been nice.
Overall, very impressed and look forward to seeing where you take this from here.
Good luck! :D
