In this update I added the ability to play the game by hitting the 'Enter' key on the keyboard so that those users without a Vive controller can now get past the menu screen. This should (experimental!) make it so that Oculus Rift players can play the application even though they will not have hands yet at this point.
Also I added the mother spider! ːMH_Spiderː Thanks for the suggestion fishhead420! I will be doing work on the mother spider in future updates, giving her a bit more life, but for now this little addition should add to the fright factor for anyone with an ounce of arachnophobia.
Also made some other minor updates, such as improved spider 2's animation path, and some UI changes.
