Stability: No bugs or crashes for me, unless you count the occasional (and in my book, easily ignorable) graphical glitches when an enemy dies. (ie. their bodies distory a lot when they die- especially the eyebats- but again, it's generally only momentary)
Content: There are numerous battles over what more or less amounts to four "zones". (Five if you count the last two TD big battles). There are a total of seven different types of enemies (though one is just a larger version of the starter enemy). There are plenty of hidden goodies to find, though most are pretty dull but important things like money. The variety is somewhat lackluster, but could be worse.
Gameplay: The concept- a combination of tower defense and shooter- has a lot of potential. I think I've only ever played one other game like it, and it isn't an h-game. That said, each of the two has issues.
For the strategy aspect, you are, even late in the game, severely lacking the critical resource- mana- to place enough objects to effectively "maze" the enemies. The "wall"-type object, which you'd expect to be the cheapest, actually gets introduced after the spike trap, and costs a bit more. It also sucks that you have no actual shooting "towers" to speak of. The only one that does any damage outside its immediate vicinity is one that only does a bit of splash damage, and you have to trigger it manually.
As for the shooting aspect, your shots are a little on the slow side- which is fine for the smaller maps and close combat, but it makes the later, larger stages a pain to aim right, especially when you keep having to look back and forth between different enemy spawn points.
And lets adress the elephant in the room- the camera and aiming system. It's clunky and very awkward, to put it mildly. You have to hold the right mouse button to turn the camera, but you will frequently end up with awful camera angles. And the fact that even zoomed all the way out, you still are zoomed in way too close- the player character takes up far too much of the screen, blocking critical chunk of your view. Don't get me wrong, her scantily-clad posterior is a very nice view, but if you want to actually play the game, that's a big problem.
Aesthetics: While it's not magnificent, I do feel some objections to the graphics I've seen from others here are unwarranted. Yes, they're a bit uninspired, but they aren't awful. So they look a bit older-gen- they're still decent. The main character's suitably sexy in the 3d battle modes. All in all, pretty middle of the road though. Not great, not awful. But it's all down to personal taste, in any case. I know some people prefer more detail and realism, whereas I very much don't. So take that into consideration when you read this.
The music and sound are fine. The music in particular is pretty well done, if pretty generic, for this kind of game.
XXX: It's okay. Not great, and could use more diversity. (Frankly, I'd have loved some tentacles, slimes, and other more exotic monsters myself, but that's just my preferences showing ;P) H-events happen when a monster gets close enough to knock you down, then mounts you when they approach while you're down. There's no "finish" to speak of, just a few minor variations in speed for whatever pose plays when they get you, and it continues until you break free or run out of health. The gallery isn't a very good one, though. You basically load a mini-battle with the selected enemy and let them knock you down- and to leave, you defeat them or let them reach the crystal. Makes browsing the different animations a pain in the ass. I hate when games do that, rather than simply having a straightforward animation gallery. But it is what it is.
All said, the h-content in this game is passable, if bland. For the length of the game, the amount of it is fine, though, I suppose.
Overall: I can't wholly recommend this one, but I wouldn't warn others away either. It's got some good ideas and it'll keep you mildly entertained for a bit, and the porn isn't too bad; but the implementation leaves a lot to be desired and it could be a hell of a lot better. I'd like to see this dev or perhaps someone else take another crack at this general concept and do it a lot better, preferably with a bit more diversity.
