It was a bit of a grind, but here's a new demo update that helps make the whole game better overall.
Bugs fixed:
It was possible to break a door before the cutscene ended, preventing the cutscene from triggering.
When movement keys are not held down while flying, inertia decays faster.
A gamepad-related bug when pressing Back in the menu has been fixed.
Optimization.
The flight system now works even better with a gamepad.
The baby has improved AI.
Shadow models have been updated.
