not sure I'm going to read this whole thread, but I want to say that this quest features a great tileset. I watched a bit of a let's play video of this and I really thought it was pretty. typos and misaligned screens bothered me -- in the first few minutes, even! how was this stuff not caught? so, what tileset was this made in? how much of it was ripped and how much of it was drawn by hand? did I mention that I think it is pretty?
I think Spram mentioned that a lot of it was custom tiles. He's exceptionally talented. The "you gonna die" levels and seashell dungeons look great, and it was a good idea to put them in as optional since their 'look' doesn't really fit with the standard quest.
