Hello,
Personnally I would have both remarks and questions:
First the questions: I am in the second world, found a lot of thing (hearts, miror shield, gloden arrow, second book) but I really miss the last glove. Where could I find it? Although I am stuck in death mountain. Found 4 entrances, have the map of level 1-2, key of level 1 and miss key of level 2-3. I have been going everywhere but can't find that higher level key for example that would help me a lot.
For the remarks I like the new monsters but some of them seems to me a bit overwhelming. The blue knights that can only be touched in the back are really hard (they move quickly and often change direction). The blue mummy can be extremly annoying (regarding potions) as we often lack money and potions are extremly expensive. As the effect of the blue mummy seems unpredictable, nearly unavoidable and can last very long, it can be a problem. The white rope is both very resillient and quick, but that's more or less ok.
Whitout any magic glass it is quite difficult to guess what we can do in the 2nd overworld, but I managed which show that is is still possible.
Overall a very interesting quest... just a bit frustrated by where I am as I still don't get how to go further.
