Your game looks so amazing!!!
We also develop html5 game and I have some question to ask:
for texture compressing, you guys use this too?
for different os platforms (like pc, ios, android), would you suggest that use different pixel formats and texture formats for different os platforms?
example: pvrtc >> ios
etc >> android
dxtc >> pc
because we now only use png files for any os platforms and worried about the gpu memory useage.
sorry for my bad english and thanks for your time for replying
