Oh, this is solid. Hidden gem. Beat'em'up is not a genre I expected to see in vore, but this works quite well! The controls are intuitive, combos are fun to perform, and the difficulty is just right.
My only gripe with it is that vore animations are bound to game overs. I hope it'll be possible to find a way to make them a progressing grab that continuously drains health instead, y'know, the kind you gotta mash out of; though that's probably difficult to implement...
Keep up the good work, I'd love to see more content from you regardless.
