not a big fan of levels that send you back to the start when you're really far in.
i know it's a matter of a minute or two but that stuff scales to the medium. i'm at that early (i assume) level where you run over disable the cameras then run back steal the red thing (which btw, based on the narrative you established and your bad explanation, i thought was more medicine, but now realize was a key to the door)
i get all the way back, hack everything again, and... accidentally trip the camera by switching and bam. start all over. no thanks.
sucks too because this seemed promising.
