Well, it uses only 192 lines, so in that regard it's not "anti NTSC".
I won't create a dedicated NTSC version though. A poll I created some time ago in the Facebook Amiga group indicated that the percentage of NTSC machines used for gaming is really incredibly small.
Unfortunately, I have to pick my battlefields when it comes to spending my time for the game, so this is really not high on my to do list, sorry..
