See, I said you were evil! Why would you even put it there if it wasn't meant to be opened? I replayed the game on hard just hoping to get that door opened - it's even shown as a pathway on the map!..
Great game though, I'm really glad you keep making them, you have a real knack for it, will replay again. Maybe not twice a year like EHF, but I will.
p.s. What's the official name for Melinda's pony-wolf hybrid? Is it Polf? Hopefully not Wony.
