Changes:

• Add Preferences option to toggle between full screen and windowed in main preferences (Manage Profile > Preferences). Going full screen at runtime also resolves the weird button behaviours if the game is built as a full screen application. Thanks to Game Dev Simplified for the tip here:
• Update to latest Godot 4 Beta (15), as that should improve stability
• Add Linux builds

Fixes:

• Ceiling cam motion in levels: Was going slow when looking down. For anyone who needs this in Godot, I fixed it by changing the Motion Mode to Floating in the CharacterBody3D node.
