Princess saved!
Good game, princess could be a bit cuter but it will work. :D
Nice upgrading system, fun to play, could be a bit more faster but its fine.
One thing that I think some people might not notice is that the game already starts when it load up,
so maybe some hints could help, or a start button.
Upgrading screen compering to game screen could be a bit smaller, I think reversed version could
work well, smaller upgrading - larger game screen, something like that.
Anyways good game, I did enjoy it,
I guess princess is worth one gold coin, but I think this game is worth four gold coins.
oh, why didn't you implement the achievements in NG?
