I've made a HUGE mistake
SEVERAL MONTHS after the the latest version of this game, it was brought to my attention (shout-out to Calunio) that this game is, in fact, NOT RTP-Independent. Needless to say, I'm embarrassed as all hell.
Anyway, I went in the project fileand changed a single line in Game.ini from:
(or something along those lines) to:
and as a result, the game should now function without RTP.
The latest download can be found here. If any issues persist, please let me know! Cheers.
