A minor demo update to fix some stuff. Version 1.0.0c changes the following:
Fix: challenge "Laser Run I" is now working - previously players could not start this challenge due to some missing content in demo
Tweak: reduced Infernal Skeleton Max HP from 100 to 75 - they can appear on first level and were a bit too difficult for new players
Content: added "Liquid Speed" Artifact to the content available in demo
