Hi~
This is Jacky. I am a professional mobile game developer, specializing in 2D games (coco2dx, c++, lua). I have been involved in development of several successful releases, with millions of downloads at Google Play and iTunes Store (Star Girl, Doraemon Repair Shop, etc). Please read my portfolio for more details.
I see this line in your specification and I have some questions about it.
Make app work for both phones/tablets
So what is the current state of the project? Does it work or one device and not the others or what?
Is it that it only works on a specific resolution and not the others? If this is the case, a auto scaling solution would require assets of different resolutions, say a 100x100 for sd, 200x200 for hd, 400x400 for xhd, etc. I would like to know if the assets are ready (You can do a force resize anyway but it would look disastrous on large devices).
PS the quoted price bases on the fact the you have the graphics ready in various dimensions.
Please contact me if you are interested and if you favor quality work over a minimum bid. Thanks.
Regards,
Jacky
