The v1.08 update for Keep Defending features optimizations for the game as well as a new control option for rotating on the spot (Rift users only).
The exploding sheep now have a limited lifespan following detonation so the level is no longer overrun by them (which unfortunately tends to slow down gameplay on the larger levels).
Staying with the sheep, the explosion effects when they detonate are now much more efficient and no longer hitch/pause the gameplay briefly when multiple sheep (in close proximity) explode at once.
The bonfires seen on Eagle Heights, The (Small) Wall, and King's Ending are now more efficient so performance on those levels will have improved slightly.
For Oculus Rift (+ Touch) users I've introduced a new setting in the options menu named "Use Thumbstick To Rotate". When this option is enabled you must press the thumbstick (on either controller) left or right to rotate your view left or right (in 90 degree steps). This is instead of using the grip buttons which some players may press accidentally. Note that you must release the thumbstick and then move it again to rotate again, it doesn't rotate additional steps if you hold the thumbstick in position.
New (Rift) players will have this option enabled by default, whereas existing players must set it themselves (to avoid confusion for players who don't see this announcement).
If you experience any bugs or problems with this latest version, or with the game in general, please report them in the group discussions (or comment on this post) and I'll try and address them as quickly as possible!
Thanks for supporting and playing Keep Defending!
