The other day I finished the Demo with 100% completion in 2/3 hours (the climbing challenge where very nice btw !) and because I wanted more, I took the challenge to speedrun the Demo so that anyone can join and have fun while waiting for the full game ^^
I just did 10:57 according to the end-game screen (8:21 according to the savefile but I guess this doesn't count all the deaths ? My parkour wasn't perfect haha - aside from spikes, I died once against the final boss)
Someone want a challenge ? x3
