– Changed flying controls: Was able to move around anywhere, now ship is always moving forward, and you can only move side-to-side, up-and-down. (always facing in the positive z-direction)
– Added timer for door closing to address no visual feedback that you were/were not going to make it out in time
– Limited amount of boost (no longer infinite) to create need to conserve it and use in a good area
– Began increasing level design complexity to provider better/longer experience
