One more demo update made:
Many were complaining about camera behavior, so I've changed it: now if something obstructs camera vision of character - we have this small transparent hole. It should be much easier now to navigate through the world
Few other changes are:
Improved hints for missions.
Bridge mission made easier (more tolerant criteria to whether bridge is considered built)
Changed lightning in Ovanox (the yellow world)
Make sure to restart Steam to get the update! :)
