I played the first demo a long time ago and loved it. It was more janky and the sex minigame was pretty difficult lol. But it showed an incredible promise. And now another demo has come out and the combat has improved quite a bit. Not a lot of animations, but they're serviceable and by the time I hit the end of the stage I was cancelling attacks to dodge out of the way, and juggling enemies to attack while staying out of harm. Even without the porn I have full faith in this dev to deliver a pretty solid action beat 'em up.
I hope that the story will be told in cut scenes... Doesn't have to be fancy cinematic cut scene, but you could probably insert a VN style break in between missions, maybe give the Commander some dialogue choices that result in the girls liking or disliking you, and then having sex with you in a different way.
