Can confirm that the game now lets you play as a VN. I had to go back a couple of saves to get to the point where it asks you though. Not a fan of the way sandbox is usually implemented and although I didn't mind it in this game, the VN option here just flows better than the sandbox.
The second chapter, after arriving in Mohoro, is pretty much a different game. A lot of new girls have been introduced but the MC is getting less action now as a successful business man with a harem, then he was as a broke student. Hell, Anna and Dora were both desperate to come to Mohoro to be with the MC but there wasn't an intimate event when they did arrive. All the new content seems fine, but my suggestion would be to slow down the world building a bit in the next couple of updates to give us some relationship events with the current ladies.
