TL;DR: Great stuff – well worth the download!
Yes, the setup is more of the same (lost island, one man, lots of girls to fuck, yada-yada...), but as they say, ideas are cheap and it's the execution that matters.
And the execution is truly great! Basically all the game is animated (yes, really) and the mechanics are simple and yet interesting enough to make you come for more (pun intended!).
There are a lot of minigames, something that pisses me off in most games, but here they are simple enough and,if needed, can be by-passed. And even if there is some assets/money management to be done, the grinding is very low (and well integrated into the gameplay).
The style of the 2D animation is really great and, TBH, a breath of fresh air from the usual diet of HS2 and DAZ assets.
The reviewed version (0.15) already provides dozens of hours of gameplay and even after reaching the "end" of each girl, it can continue to be played.
Last, but not least: didn't encounter any bugs/crashes (win64) and the same can be said about typos in the (really well written ) story.
