If I had to say anything positive about it, is that I liked how the witches' forest looked, and 1 or 2 other areas (of which I only remember the forest, so they weren't that impressive either). But a map doesn't make a game, not even the music makes up for the terrible gameplay, and I held the same opinion 8 hours into the game as I held it 20 minutes in.
Sure, this depends on the person, but the game is bad, and it's extremely repetitive so it's not like that really makes that much of a difference. If it actually had something else that kicks later in the game, I'd agree with you or OP that you have to wait for it, but it actually doesn't.
20 bucks is mostly why people really shit on it, it wasn't worth that much. Had it been cheaper, people wouldn't have been so harsh.
