Pushed a new update. Changes:
Made good optimizations on text drawing issue and also added an option to turn off the particle effects => sands flowing to the lower-right side of the screen, for lower-end devices. Now it should work better.
Also I found an issue that causes the game loading hang at 99% and this is specifically related to internet explorer 11. There is a workaround but I need to make lot's of hacks in the game code. So I just added a warning message for those people who use internet explorer.
Finally, improved the cliff diving level a bit.
