This is without a doubt the worst designed RPG maker h-game I've ever played, and I've played a shit ton of them. I don't even know where to begin so I'll just say the art is good, some of the scenes are passable, literally everything else about this is a holocaust from which only the dead can know peace.
You are not the first and I'm sure you won't be the last to lambast this game;
I have also played a lot of games from this site and Warlock and Boobs is currently my favourite;
It is an open world RPG in the style of games from the 1990s (rogue, nethack, ADOM);
The MC starts with little idea of what's going on or what to do;
Right from the start the MC can easily wander into areas where they will be quickly overpowered by adversaries;
Progress is not primarily intuitive but more a case of trial and error;
Replaying (and taking notes) will allow the development of strategies which make the game easier;
Clearly this is a style of game some dislike - and others enjoy;
