After enjoying the first game of the same author Apocalypse Mutant Erotica as much as I did, I quickly went and bought this game as well. It is much longer than the first one (~4.5h). Render quality is still not the best (mediocre character models, empty background, very visible difference in quality between still images and animation, animations themselves are a bit stiff, etc.). But I enjoyed the game nevertheless.
The added resource management system (time and money) was fun and not grindy at all. I achieved the harem end (which I assume is the hardest to achieve) in my first playthrough (just save before the final decision to see all the individual ends as well without playing through the whole game again). But even if you don't manage to achieve that in your first playthrough, there is a New Game+ where you start with a lot of money and sped up progress.
In my opinion, story came a bit short in this game. Every piece of story was clearly just setting up the next sex scene. But I still enjoyed it and its characters. Also, the humor from the first game is still present. I would have liked to see more scenes like the one where you go out with Boss, Janet and Leah. Those dialog minigames are where the humor really comes through and shines.
All in all 2$ well spent. A shame that this developer is not better known.
Edit: Also, that twist in the Aisu ending was so fucking hot ;)
