I see in your post from February that your game Clyde it was almost ready. As I see in your last post, I guess you didn't publish yet, isn't it? Some tips?[/QUOTE]
Unfortunately I didn't work at my game for two months due to a bad case of measle (!!!) with severe complications. Now I'm polishing the game. I hope to release it in september, but I'm also waiting for a stable cocoonjs update.
You can use more than one layout. I'm using 40+ layouts and the game runs fine (except audio problems, but they're not related to the layout number). It might be a physics related problem. Since I don't use any physics object in my game I didn't have any issue.
