Build 0.3.4 (07/25/2015)

• Added music (and separate volume settings for it)
  
• Optimized camera setup in order to increase game performance on low-end graphic cards
  
• Slight changes in spike placement and platform length (in order to make some places slightly more forgiving) on levels: II-1, II-4, II-12, III-10
  

I should note that while we've made some tweaks to make certain places "more forgiving", it does not mean that we want to simplify the game. Those were the places where you could die even if you did everything right, but were off the spot by a pixel or two. It was an unfair difficulty. And those places are still hard, but they do not require pixel-perfect positioning any more.
