General bug fixes and tweaks

• reduced the max active creatures in Survival by 1 (makes it a little easier)
• pressing Y on the controller to start a NG+ now works
• added new option to disable Fog Blur (disabled by default on Steam Deck)
• performance fix for Steam Deck (previous update limited it to 30 FPS)

Note, on Steam Deck the FPS are limited to 30 FPS when showing any menus (except for the Options menu) to reduce heat & battery usage. Joypad tweaks to make it easier to aim:

• joypad sensitivity changes (i.e. smaller differences between each sensitivity option)
• reduced the Y axis joypad sensitivity
• increased time it takes to go to full accelerated turn speed
• reduced the max acceleration speed
