This was a very fun game, although I didn't like how confusing exploring the scenaries can be, I think you should have done the same thing Shadowgate (Game Boy version) does, and draw only one image per room regardless of the direction you enter it from. Also I had to look at a walktrough for the end, since I never found the attic door by myself! again, knowing where to click to explore can be confusing. Shadowgate also solved this very nicely showing the exits in the corner of the screen.
I used savestates to replay the bosses quickly (bought the rom and played it in my DS), they are hard!
Keep doing the good work.
