Well, a game breaker exists in the 1.05 version. Imagine that. I'm not so sure, but I think if you download the newest versions you can carry over your save files... Maybe someone can clear that up for me. I merely fixed a switch fix. If you saved AFTER the screw up, however, I think your file is dead. And again, I apologize, but I think we can all agree at this point I just suck. Now I remember why I never released anything for 10 years, the game never seems to work for others the way it works for me.
Anyway, there's a version with the RTP and a version without it. The RTP included one should fix those game crashes people without the program are having.
