TYSM for all the kind words. I want to keep it pretty standardized for all the bosses so there will be one gameover screen. I'm hoping to have some way of having some aspects of both phases before and after. Haven't planned a vore themed attack for phase two yet but I'm trying to see if there's a way to incorporate it.
As for software I used to use ClipStudioPaint but ever since I moved to Linux I've been using Krita. It'll be a really, really long time before i can make this happen but once the game is done I want to put out all the assets and game files out there for people to use and learn from. Hope this helps!
