The gameplay is connect-3. There's a leveling up system, spells, special quests and the opponent has a few counter attacks. So even if connect-3 isn't the most exciting thing it's done well enough to support other aspects of the game. The dialogue is rubbish however. I know there's not be much to expect when it takes place in Harem World but still..
I lost on my third fight twice. I don't know if I'm missing something because I couldn't even get her down to half hit points.
