First of all, I think the tutorial is really well done! It's intuitive and explains the mechanics of the game really well!
As for the combat scenes, they're pretty well done, and the fact that they're different depending on the enemy means that you can take a different approach each time.
As for the lewd scenes, they're really, really hot and well done too! It's a pity we're only allowed two mistakes, though. The same goes for the storage space at the start, which is too small. I think increasing the character's storage space from 10 to 15, for example, would be a better idea, especially when you're collecting lots of items and exploring.
Anyway, the game is really excellent! And I can't wait to see what happens next with this new project!
