It's cool how well you managed to combine pixel art with 3D environments. I like how the player has a subtle glows, it does a good job of blending the two styles together! The sprite art is pretty and you've made some very nice animations.
The controls are simple but functional, though there do seem to be a variety of bugs of opponents being able to damage or grab you from strange distances.
The music reflects the action. There could probably be a few more sound effects to add some extra flavor, especially for the sex scene.
It's honestly very close to being a short and fun fighting game, so I hope that you'll revisit it for a bit after the jam. The arena and characters have a really cool and distinct look, and I'd love to see them in full action!
