I do think the list of tasks would be much more manageable if we were allowed to do them in whatever order we want so we don't need to do loops around the rink, Or do the exact same order if we manage to die. Also I feel the filter is way too strong, and also makes me wonder if this is meant to be some form of found footage?
SORT OF SPOILERS BELOW
Story wise there's a lot of curiosity here but also not a whole lot to chew on; It would be cool to have some more hints as to what happened on the night that the people got turned into the mannequins. From what I can see its some sort of ritual or cult activity? Would be cool to maybe see some newspaper clippings or maybe finding a tape in the managers office within the rink. Small stuff like that would really add to it.
