The unlock path for the first robot is just punch punch punch, then it falls over and you get a little flash of static. I kept pressing A and J at the same time because I thought maybe there was a combo, but no, it's just one button for punch. The school uniform physics are there, the skirt flips up when you kick, and the robots have these weird tube arms that grab at your chest if you stand still too long. I spent way too long on the second screen trying to figure out if the X button did anything besides the obvious. It does. It's a stamina drain and the robots keep walking toward you while you're doing it, which is either funny or annoying depending on how many times you've died.
The arcade feel is real. You move left to right, there's a score counter in the corner that I still don't understand, and every third robot has a different color scheme like a palette swap from an old fighting game. The kick has more range than the punch but leaves you open, so you end up spamming punch and then backing off. One robot grabbed me from behind and the animation looped for like four seconds before I could break free. That was the first time I actually laughed at the game instead of just clicking through.
The preview ends after three screens and a boss that's just a bigger robot with more health. No save, no continue, you just restart from the beginning. The masturbation button feels tacked on, like they forgot this was supposed to be an adult game and added it last minute. The robots don't react to it, they just keep walking. I wish the full version would add a block or a dodge, because right now the only defense is walking backwards and hoping the robot's grab animation doesn't trigger. The hentai tag is doing a lot of heavy lifting for what's basically a Shinobi Girl clone with worse hit detection. I'll probably check the full version when it drops, but only because I want to see if the robots ever get more creative than "walk forward and grab."
