Turn Based Strategy Grids [Released] [Many images]

So questions -
Can this do multi-level grids?

How large can these grids be before performance drops?

Is Asynchronous multiplayer planned? (Multiple Players Move, attack, etc. at once and the server decides the outcome based on numbers.)

Can this handle air/space units?

Last but not least how much will this cost?

Just curious,
