I would definitely tag this as "Story rich". The lore behind it and the depth to all the characters was astonishing!
Jokes aside, the concept made me chuckle and I thought it was an original take on this. It's fairly hard to direct the... mouse wheel? and the lack of checkpoints (even for the beginning of levels) was a bit unforgiving, but I enjoyed it. Would probably be interesting to see other kinds of interactions other than "death" in the map (maybe I missed them? I didn't complete all the levels, it was hard enough finishing the first one and then having to do it all over again after dying in the second one :D).
