Hey there! You can read the recent development plans and news here.
After some complaints about bad performance on firefox, I decided to dig in deep. It seems that the text drawn with native html and the composite operations for light and particle effects are incredibly taxing on computers without a decent GPU. I'll try to fix as best as I can and also put an option to turn them off alltogether.
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.
