Just played the game (old version I believe) and I gotta say that this is perhaps the first game in which not only do I love the hentai quality I also love actually playing the damn thing in the first place. I run into quite a lot of games that are usually pretty clunky to play but are heavy on the H (I mean, sometimes I actually DO want the hero girl to actually pass the level, you know.) and this one's just great, also really nice in letting her stay down when her life is depleted until either you let her get up herself (if you have lives still) or until someone "comes and gives her a hand". I'm going to keep an eye on this one, it's simple yet fun and thoughtful. Do have a few wishes though, one for any damage to her to knock her down completely instead of just pushing her back, perhaps even now when she's KO'd you could have her breathing and panting heavily as she lies defenseless. I think that was mentioned before in this thread too. Also a pause button would be nice (if I gotta do something outside the game) and the in-game sprites were just a bit bigger... (oh, and I'm another one that managed to get killed by the birds somehow...) Still great game, spent more time on it than I thought I would.
EDIT: Because this wasn't listed yet, just one thing; While jumping you can do a nice dive kick by pressing DownBack or DownForward and the jump button again. It not only helps moving faster but she can bounce off of nearly any enemy with it save a few. It's possible to still get hit though if you aim it wrong, or even if you actually hit them.
