Ah, the keyboard controls...
I initially had them similar to Minecraft's swimming, but then wanted to make the camera a bit more dramatic (edit: and free to look around). The terrors of camera design that followed were not for the faint of heart. (X . X)
Did you know there are multiple books about how to make videogame camera systems? I didn't until two weeks ago! (@ o @)
I ended up putting the mouse-controlled turning back in pretty last-minute, to hopefully get the nice controls and dramatic camera. Effectiveness still in-question.
Glad you enjoyed the game with controller! Thanks for playing! (^o^)/
