No keyboard/mouse presses are detected by Input class.
We have a simply Debug.Log (Input.anyKey); called in Update method. Basically, each frame if any button is pressed this prints True, otherwise it prints false. The bug is that no matter what we do False is always printed. This bug can also be reproduced with other methods like Input.GetButtonDown, or Input.GetMouseButton
To reproduce:
1. Create a new project (The attached one does not work)
2. Create a script in it
3. Insert Debug.Log (Input.anyKey); into Update method
4. Save & Enter play mode
5. Press any key
Expected result: True is printed
Actual result: False is printed
