The prefixes i wrote about was more of a convention than anything in the script. It was never intended to produce more than just Tiles and Sprites arrays.
But this sounds like a fine option to have, I'll take a look.
You can also consider writting macros like so:
#define EnemyT(n) Tiles[TILE_ENEMY_##n]
#define UiT(n) Tiles[TILE_UI_##n]
Thanks for using the tool!
