All-in-One Mahjong on Mac
While Samsung’s developer portal is somewhat buggy, their discount feature worked great for All-in-One Mahjong game.
The game is #2 (or #3, depends on country) in Top paid right now, just a week after the discount.
I had similar positive results with Amazon FAD for both All-in-One Solitaire & All-in-One Mahjong games.
Even though Solitaire had some critical bugs and thus received a lot of negative reviews, I had an increase in sales afterwards.
First demo from Rainbow Lines game.
The code is pretty much ready, although this demo lacks a lot of things, like graphics, animations and sounds.
Ah, and cursor is displaced on the video for some reason.
