 My problem is that, in my game, each screen is 30x20, and I have
about 100 screens, so my tilemap contains 32*20*100 = 60000 python
objects (integers).

 If each integer-python-object takes 16 bytes, this makes 60000 * 16 =
almost 1MB of memory just for the tilemaps...

 Using array of type H (16 bits per item = 2 bytes), my maps take just
60000*2 = 120KB of memory.

 After that, I just will access tilemap data for reading (i.e.  value
= tilemap.GetTile(x,y)) ...

 Do you think I should still go with lists instead of an H-type array?
