Some important fixes in this patch include:
Positional teleporting - missing GO icon
Sometimes when you were asked to move over the GO icon during a positional teleport, the icon would be missing. I couldn't reproduce this but believe it was due to an incorrect startup sequence. It shouldn't happen now, but if it does: 1) please tell me. 2) the reset button on your controller will allow you to return to the last check point.
Teleporting into walls
If quickly teleporting around a room it was possible to end up in limbo due to being in a wall when you completed the teleport. You cannot teleport within 5cm or so of a wall now, which should fix the issue.
FPS-mode stuttering
When in FPS mode it would stutter as you moved along a sloped wall. It should now move smoothly.
Other minor fixes are included too.
Thanks for reporting the issues.
Also, I wrote some notes about the difficulty of the game and my plans. Feel free to comment.
