One of the more tedious games I've played...
I disagree. The game is fun and the premise is nice. Most of the clunkiness is due the engine, unity is somewhat subpar.
If the game could been better? Of course it could, like I said above I would much rather have more scenes with the girls already in game (specially family members) instead of adding characters here and there, since it removes the importance those girls have in the plot (makes the relationships feel extremely artificial and utopious, even for harem games) but I think the game is pretty fun.
If by tedious you mean some tasks, yes that I agree. It bothers me a bit that some tasks are nearly impossible to do without hints. The bathroom key for example... holy molly, that was so hard even with hints, I hated that specific quest. Some of the others were also "meh", but not as frustrating imo. But the dev is making efforts in that regard, I recall the first release being extremely clunky and hard to play, the polish is much better nowadays.
I also don't know if it is the first project from the dev, but if it is, that explains the increase of quality the more you play.
edit: noticed on steam that it isn't, although it is the first on steam. At any case, the price seems fair for the content the game has atm.
