Opacity Zero 1.1 Update !

Apologies, I hope this helps: 

Mouse controls in-game are disabled after going back to the main menu, and entering the level again. Able to click and hold to look around as a temporary fix, so looks like mouse capture is in wrong setting. Game must be restarted to be playable again. Initially experienced after completing the level and restarting, however also happens without a victory screen. 

Branches after rock parkour can be difficult to get up successfully - needs either terrain smoothing/specific steps/jumps positioning. 

You can skip the second parkour set by walking around the fence at the top of the waterfall. 

Difficult to understand the direction you are meant to head to - perhaps a compass/checkpoint marker at key points would be useful. In the current build, only three would be needed - the start of the course, the wooden platform protruding from the cliff, and the end goal. 

Arm movement for "running" would be a good addition, instead of holding an invisible weapon. 

FOV slider required - to make sure people can mitigate motion sickness. 

Graphics settings indicator needd to show current setting that is enabled. 

Controls are good and intuitive, albeit the jumping being slightly "flighty" at times. 

Good theme (perhaps player model/hands changed to reflect)

Map size is good, however would be nice if the length of the map could be increased. This can be done by making the map thematically narrower and denser, and utilizing more of the map space: 

E.g. A map of a forest and waterfall, with branches of the tree being the majority of the platforms you use. A second map being a farm - using fences and scarecrows and farm equipment as the platforms. A third map being a populated village, with many houses. A fourth being a campsite, with tents and fires and more adventurous rock climbing being used. A fifth being a moving river jumping boat to boat, or to various rocks or boat-wrecks to achieve your goal.
