finally, I was waiting for this! I was thinking... why if I make canvas app I can't play from mobile? finally they made it! and if support all of sdk (like php, java...) I have everything ready to go for making a good game!
this is a realy great news!
Ashley, take a look of this, this is really powerfull and construct2 is perfect for that! if is possible to make games for facebook on mobile will change everything! expecially if you can sell the game or if support the payment like the canvas app
