I'd like to point out a little gem I just purchased yesterday, here's a link to the DLsite page:
The trial version has a miniscule amount of content but it does let you go all the way to the first boss, and along the way are 4 different enemy types.
The full version is worth your time, has about 9/10 different bosses and 20+ enemy types, each with their own CG scenes if you are defeated by them. Also right after the part where the trail ends, in the live version there's a portal that takes you straight to the recollection room where you can go ahead and look up all the enemies, their CGs, and even replay fights.
I'd like to point out some things for those just who are interested in the game but get tripped up by the combat system. It's turn based, and when the icon hits right before the red bar you choose the move you want to do to the female opponent (I believe it's something along the lines of feeling them up in various ways). The first four commands in the drop down are your sexual moves and after that are pretty self explanatory (spend a turn defending, using an item, a desperate kiss move that I'll get into later, escaping, and just plain surrendering). By each sexual move is a number that corresponds to the amount of SexP (is what I'll call it) you need to perform that move. The amount of total SexP you have is under your HP bar. Enemies can utilize moves that take SexP from you or inflict status effects that double the amount of SexP required to perform a move. If the gauge hits 0 by either the female taking away what you have left or you using a move that would make the gauge hit 0 or below (you'll still perform the move btw), you'll be stunned for a full turn. Usually in that turn the female will get the drop on you and she'll go ahead and pop you off, regardless of your HP and make you ejaculate. There's items to replenish both your HP and SexP.
The last thing about the battle system is under the time bar when you're choosing a command you'll see 4 numbers next to some lettering (usually colored red, grayed out, white, or blue). These correspond to the sex move you perform and it's in the same order. Red means she's weak to that type of stuff, blue means she's resistant, and I haven't figured out what white and grayed out mean. The numbers beside them I totally haven't figured out either but I believe if you use a sex move and the corresponding number is about 5 she'll immediately counter and make you ejaculate in that turn instead. Also bosses can make the numbers go "?" so it's a guessing game from that point.
That's pretty much all I can help ya with. I dunno what most of the items do (although HP and SexP up is self explanatory), I dunno what all the skills you distribute SkillP are for (although the last one increases how many times you can ejaculate before you lose a battle, IIRC the first increases HP and the second increases SexP), and I have no idea how the purchasing of equipment works or what the old man at the Guild is selling. Oh and against bosses, they usually try to settle an agreement with you (usually resulting in rape) when you've got them at 50% AND before the battle is over. The second option is the one to choose if you want to continue the fight/end the battle, the rest are different versions of "I surrender" and you'll get H scenes. All the options lead to the H-scene but usually the female has a different facial expression.
Honestly a game I think is very worth a translation. I've rushed through it and beat and it was well worth the $11.
