Glad you enjoyed the tracks. I'll probably remove the links just for the sake of identity-protection. Not a lot of other ways I can support, other than encouragement. Keep up the good work, and drop me a line when you get to the next stable-ish version of the patch.
Another suggestion that you may have already acted upon: Additional areas on the 1000 AD map that serve little-to-no purpose. Nothing dungeon-sized, just more places to go. I never really felt like there was enough going on in the "Present" to keep me coming back to it, and I know that's probably just my mind playing tricks on me. What I mean is, it felt the least unknown, and didn't necessarily provide that urge to explore places unknown on the map.
So for example: an entrance to the forest in 1000 AD where the cathedral was located 400 years prior. It takes you to a small forest area, where maybe you fight some stronger monsters that would kick your ass at a lower level. Or an entry to the mystic cave. It has a smaller layout because A) let's say nature happened before Frog opened it, and there's a tiny alcove you can go into, or B) nature happened after Frog opened it, and because of a landslide, there's a tiny alcove you can go into. Inside, you fight some bats and there's a guy you can talk to who says something interesting. While I like the idea of going all-in for 1999AD and adding sidequests, sometimes it's the smaller, inconsequential additions like that, that can really boost the sense of freedom.
