Feel free to download and use the game art, sprite and background. I have created them to help game developers. Please do not download them and sell. If you need a specific game art, go ahead and contact me by posting a comment in my blog. I will try my best to create the game art and put it up here.
Use cocoon for building android games. It produces smaller files compared to Intel xdk.
Use Intel xdk to build iOS games. It produces smaller ipa files compared to cocoon.
Typical file sizes for apk:
coccoon = 8 MB, intel xdk = 25 MB
and for ipa (iOS) :
cocoon ios = 20 MB, intel xdk = 4 MB
Why Intel xdk apk such big file, because you need to embed crosswalk browser. If you don't use crosswalk, the file will be very small, but virtually unplayable because of unpredictability. You could use shared crosswalk to reduce the apk, but, that might put off your players who may not like downloading the Intel crosswalk separately (about 25 MB).
