While I can enjoy the effort put towards making the mechanics better (for the most part), I would have more appreciated if the modification was just that on it's own. To be perfectly frank the modified palettes, sounds, and areas should have been relegated to their own external mods/expansions rather than being bundled with the main mod itself. I don't hesitate to say I personally think most of the new tilesets look rather ugly, out of place, and wholly detract from the cool-coloured ambient atmosphere the original one made so well. The sound changes from right out of the gate I found queer at best, and repugnant at worst.
I'd absolutely love this mod more were it just an expansion of the original's mechanics and did not touch it's palettes, tiles, sounds, or map.
Maybe what I played was a modified version because I see nary a texture touched here.
