Hi there! That's right, the game will have its share of nude scenes and even H scenes, even if there won't be an excessively large number of them. I'm designing this game more on the moe side, not nukige. And, as you say, Act 2 will have the first nude scenes and something more...
The English version is still at the last stages of Act 1, so it doesn't contain nude scenes yet. But time will provide.
I hope you enjoyed the game so far. See you!
