Overall a good game. The minesweeper had enough safeguards to cover for random clicks. Clear spaces to charge up your hacks, use hacks to clear away mines and get attack points, use attack points to see the hentai, do enough hentai to cause an orgasm, orgasm gives you a shield that protects your health.
My advice is to always try and start a stage with a shield. Some of the later stages have mines that can kill you in one hit if you're unlucky.
If you don't have a shield, click around the low numbers. That way if you hit a mine, it'll do low damage.
If you have full Hack points, use them, even if you don't need it. That being said, be careful how you use them.
EDIT: It also seems like some stages have an ending that doesn't play during gameplay, but do appear in the gallery. I'm not sure if every scene has one, or just those two. Specifically, it's stages 1 and 4 that have them.
