Just... one... more... castle...
Fortunately, I´ve just got killed by a cannonball and I have a short break to write a few words of commentary.
In terms of gameplay, Lure: The King's Gold is almost flawless, a well designed combination of fast-pace action and tactical planning, where proper choice of targets is as important as nimble fingers. On the graphical side, all objects and sprites are drawn in simple, but not amateurish way, although I have the impression that the campaign screen and character portraits have better quality, like they were made by another artist. My only complaint are the castle turrets, which do not match the medieval setting, simply looking like a WW1-era bunker turrets. Maybe replacing them with simple catapults or ballistas would be a good idea.
Story and dialogue... Maybe this will sound blunt, but they need to be rewritten from a scratch. This kind of game doesn't need sophisticated writing, but the premise of the story is silly: an old man dragged away from his home by the king's guard and then ordered to storm castle walls with spears, while the rest of the army simply stands in the back, playing blocking troops with their halberds. And I'm not even mentioning the gorgeous princess falling in love with an old peasant... As for the dialogue itself, not only it lack wit and humor, but it's obvious that it wasn't written by a native speaker ("God's greetings", really?). My suggestion: re-think the story, write the dialogue again and have it checked by a few persons (I could volunteer, though I'm not a native).
Despite the problems with writing quality, the demo version is very promising and I hope that you will finish it soon. What about publishing another demo version with more levels in the meantime, let's say in three months?
