I forgot how long I took to play it
Not sure,

It was very difficult to play it when it came out
Everyone who came in was just shocked at which pace i came closer and closer to the end
I believe I cheated myself a bit when testing
which ended in a three-way-boss-race at the end
maybe 6 hours and I had 50% already done.
Yes, he played all day and grinded the mod
literally the demon got summoned and haunted the whole level just to get second finisher by 2 hours after Failentin
I took very long at the beginning, at the second part
when he and someone else had a 2 week headstart befor me
Imagine: The time they needed for let's say 70-80% of the mod (2 weeks), was done by me in roughly 12 hours.
The thing is I don't do such things bc I want to experience every corner of a game
Totally worth it. Not everything must be done quickly
I also love things to collect
This was one thing that was absolutely crap about slap them all (bc no collectables) and even XXXL bc they have been hidden very badly
