While not without a few flaws, this game really did the trick overall and deserves a full score by my reckoning.
Pretty damn unique as far as adult platformers go, there's no combat in this game. At its core it's a situational puzzle game, where you find yourself in various sticky (sometimes literally) situations that have a solution to escape from. There are also a few light platforming segments, but nothing too egregious (the controls are good enough for basic platforming, but wouldn't stand up to the advanced stuff).
The adult content was also handled really well; while it's a classic 'raped when you lose' scenario that is so common with sidescrollers in the adult genre, this game makes it feel like it's actually a natural part of the game instead of something you have to go out of your way for. Enemy encounters are set by scenario, and generally I would just barrel into them on purpose right from the get go to get their scene. As soon as the scene's over, you get reset to a checkpoint (and checkpoints are very generous). So while the sex scenes are 'bad ends', they're clearly meant to be 'collected' naturally throughout the course of gameplay.
And as for gameplay, it was the perfect level of puzzling for what it is. I never felt frustrated with the puzzles, but rarely did I feel the puzzles were gimmes. I felt like I earned each level of progression I did through each scenario in a satisfying manner.
Story-wise there isn't jack shit beyond 'you're a girl lost in the spooky woods, get out un-raped'. Literally that's it.
The quality of the adult scenes are solid, the animation is a little lacking for my taste (I prefer more movement for that extra layer of dynamism that only 2D animations can achieve) but they're gorgeously rendered and not bad. I just found them (mostly) mid. BUT. There's a great variety, and three types of scenes: in-game sprite scenes in which the character/monster models are used, CG scenes in which there are static images that you can advance with a button, and special fully animated 'movie' style scenes (the best ones for me, but sadly the least common). There are a nice variety of monsters/critters to defile your character, and most of them (if not all) have more than one scene (so be sure to get caught on purpose every time you encounter a creature, even if you've seen it before).
It's not without flaws; as I mentioned I wasn't fully satisfied with the animation quality (the art quality is fantastic, though), and I did encounter one progress-halting bug. Selecting to go back to the last checkpoint from the pause menu didn't fix the bug, but going out to the main menu and loading did help (and the generous checkpoints meant I was right where I left off). So yes, that was a problem, but my experience with the game overall left me fully satisfied in spite of any solvable setbacks, so I definitely consider the cons easily non-factors.
Good stuff!
