There is one unique variation with Tonkin. If a goblin is performing cunnilingus Tonkin can initiate a blowjob rather than the standard titjob that regular enemies do. Don't think there is a way to get him to fuck karryn though.No way to revive the boss currently (unless there's some save or game editing that can do it). Honestly there's no difference in anything when fighting him at high slut level, besides giving him handjobs when you unlock that. The only thing that changes is a reference that you're rematching him if you've lost before and about 6 different end dialogues as you continue to lose until it repeats the last one (implying you're losing on purpose, exc.).
I decrypted the image files for the game into .png files and one of the image sets is a kneeling BJ scene (not the one in the bar) with karryn sucking and giving handjobs, though I have no idea how you trigger it if it's even possible. One of them is green so etiher a goblin or orc. There is an orc enemy in the enemy and troops database but not in the game yet. Unfortunately I haven't figured out how to edit the project in mv and launch it as a project so I can't play it if I make edits to it. Maybe someone who knows more could provide some insight.
Probably my biggest "issue" so far with the game is that enemies are really one-track minded. If an enemy starts fapping and talking to karryn they're going to keep doing that until they cum or karryn taunts them. Many would rather talk to her than do anything even if she's on the ground. Enemies sometimes never choose to strip karryn's clothes which is annoying but thankfully regular attacks and H-attacks strip them over time as well. If karryn enters a battle with no panties this issue with stripping is exacerbated. Idk if anyone else is noticing these issues as well. Still, looking forward to more of this game, it could be utterly fantastic with enough content.
