First problem and I don't know if this might be something related to my PC only, but, when you start the game ( by selecting the 'Begin' option on the main menu ) it takes you to the debug room, I think. It's a room with a stool, a mage-dude and a cactus.
Second: When you fight with the dragon, in that same debug room ( I wanted to try fighting him, I was too curious not to ), when he casts 'Magic Missile' a message appears saying something like: "RMk2003 was caught in a loop and will terminate the current action".
Thank you for your attention,
