No, this game is not perfect, but it does have heart. There is great humour and whimsical feeling in this game. It regularly made me smile while playing.
There are some things to know that might make your playthrough more enjoyable:
- There are various quest lines (not started at the guild job board), unlocking various important things. They are not always indicated (particularly the start of the quest line).
- Even trivial quests, like bringing a cat back, are part of unlocking major features (crafting) that also make the combat much easier.
- Farming materials for upgrading your equipment makes a huge difference, particularly if you're not doing a slutty run.
I would call this game a rough diamond, and is a good match for you if you don't mind playing this like a proper RPG (farming materials, grinding some enemies, doing loads of quests) with good lewd content as a bonus.
