Hello @Geo and @Ugotsta and @simwhi and @GenkiGenga...
Thank You for Your kind words, and suggestions. Finally we published our game into our Tales4fun.com site, and 2 days ago to the Chrome Webstore:Who's knocking the door? memory game
and to the Scirra Arcade too:http://www.scirra.com/arcade/addicting-puzzle-games/1194/whos-knocking-the-door
I our site there were only a little problem with server caching, what solved in Appache, but the fullscreen mode worked prefectly.
In Chrome Webstore I've paied the 5USD initially fee, and got my app in online preview mode in minutes. It functioned good, but have a little problem in HighRes display: its little "pixelly". I hope that C2 will have some tools to make easy to provide normal and HD versions (by normal, and full/high resolution images at export). Additionally I've worked alot with the promo images to make for Chrome WS, but afer a day they refused the small and medium one cause of "it have too many details". I think it were cause i placed the title on the promo images (as shown in the official tutorial).
We got 8 install here in 48 hours.
The final experiance were with Scirra Arcade: the uploading (updating) process is easy and fast. Unfortunately I've met a bug after the accept of the game: the game were optimised for different screen sizes from 1.3 to 2.0 aspect ratio. This means that it works fine when run in fullscreen-scale mode in 1024x768px and in 800x480px too. But for some reason it do not works in SA.
Found in the SA upload tutorial: "doesn't support fullscreen games yet", but can't find this restriction in the Upload game page.
We have 14 plays in some hours, but got 2 star rating from 2 users... :(
I've uploaded a smart bugfix, but dont know if this 2 stars will completly fire off the game in SA.
