This film is writer Makoto Ueda second attempt at playing with just two minutes - already known for creating inventive stories with a twist, this time loop adventure was proceeded three years earlier with a Time Machine looking two minutes into the future.
The viewer will quickly notice apparent continuity issues in respect to presence/absence of snow in the repeating 2 minute periods. This was due to the highly erratic winter conditions during shooting. To their credit the film makers actually embrace this "glitch" by having the characters themselves remark about the radically changing weather and ultimately appear to accept it as an effect of the loops on the environment
