That's a really nice game for a first one. Despite some typos your writing is pretty good (maybe put the name of the characters when they are talking, I get the "" is for Katerine but sometimes I forget ^^' )
You should definetly check out RPG maker engines it would help you a lot in making longer games with interactive narrative and saves you the time of making movement mechanics and a combat system.
They do be a bit expensive for what they offer but there are some cracked versions out there that do the trick ;)
