I...beat the whole game, including bonus dungeon, with zero H...I was having too much fun. Didn't even realize you could upgrade past lv7 (need to do H events to upgrade further)...anyway I explored some of the H, which was fine, but I honestly found the gameplay loop super fun. Little bit of strategy and planning, with a speedup button, you don't even mind losing levels restarting, the game is very winnable but still has a lot to it. And admittedly I liked the characters and even the story. Super surprised with this one.
