Thank you very much! Both I suppose... first I just had a missile in frozen time and no idea how to get rid of it, then I thought of the unfreezing mechanic and that the missile would be turned with the lift and a rope made of clothes, then I somehow connected the dots changing my mind and streamlining till the last minute :).
Found these random scribbles from day 3 or so, not much there, but I guess that's how it started :)
