Hey there man, amazing job. When I first fully played the game in its original state, some elements seem to be lacking. For example the ork eggholes. When I first played I couldn't believe that they never made an egghole party member capture, it was such an easy road! And from what I have read in your draft file, beautiful work. The original lacks that "party enslavement/capture" element. Which is weird, because the game like screams that element. It need more things like that party corruption in the demon spire (but in the other themes of course). So yeah, really appreciate your work, keep going at it.
Also while you still here (hopefully), I found a bug or whatever that was. So in the slave market, when someone activates collar on the party member, if you retreat out of battle and go into the character menu and try to see characters (through status, giving potions, etc.), there will be no pictures of party members (of those who were collared) and you wont be able to leave the menu. The game will also give an error something in the lines of: "img/pictures/JylaCol2 can't be loaded" (it can be with any character). I decided to check out the files and discovered that there are no "JylaCol2" in those files. So I guess it's trying to load picture that doesn't exist. So that's the thing.
Sorry for the wall of text, just really like what you're doing with the game, and wanted to help. Also, do something more with orks, like corruption but transformation to ork or something, the ork parts are lacking, a scroll of transformation is not enough, should be a legitimate way to do that in battle or something. That of course if you want to, your mod, not mine.
