It downloads much faster if you buy it from DLsite—it's inexpensive, and so is the first game. It's compatible with Windows 10 or 11, but you'll need RPG Maker VX Ace to run it. (I bought the RPG Maker bundle on Steam during one of the sales.) So far, I've gotten three side characters pregnant, as well as two of the main female characters—Rinko and Eri. I find myself switching between the translated English version and the original Japanese version. The save files work across both, so you can use the same saves regardless of the version you're playing.
