Man the guy developing this game must be having a laugh, I swear. Dude originally released a flash version of this like a decade ago or longer and it legitimately had more features than the version we have today.
If the dev is reading this: You need to figure out something new dude. You've been milking this game so long that it's all dried up. Also dev, you know Flash is dead, right?
EDIT: I was wrong! Kasumi Rebirth was actually released in September of 2004. Holy shit this dev is taking the piss. He's reskinned an 18 year old game and re-released it with fewer features than it had two decades ago. That's right folks, this game is TWO DECADES OLD. I guess play this if you want to know what most Newgrounds H-games were like back in the early days... but actually, don't do that at all. Just go play Kasumi Rebirth instead, it has more features anyway.
