I just finished the game, and I absolutely loved it! It's got everything you could want in a game: adventure, fun gameplay with a variety of well-designed minigames, the bondage aspect, of course, which I absolutely love, but also charming, well-written characters.
There are so many great little details, like the characters moving their lips when they speak. It's such a simple thing, but all these little touches add up and make the game feel so much more immersive.
Honestly, I had a lot more fun playing Didnapper than I do with all those soulless, bland AAA games that keep flooding the market. I'm looking forward to the sequel far more than I am to another crappy, repetitive GTA.
