Well I used to love this game. I lost my save after a power outage. None of my other Kong games were affected. I'll try back someday when the dev creates a viable game backup strategy like exporting to text or cloud backup.
First, you need to allow the reporting of bugs, the Report Bug link goes nowhere. Second, you need to retain the quick-save data after the game is loaded. Delete it when you die, if you are stuck on the whole "Death means game over" hardcore thing. I just lost a few hours of gameplay because I closed my browser and can't load my last quest. Deleting the save game just after load means that if you close your browser, you lose your entire game.
Otherwise, a great game. Needs some balancing to magic, magic is worthless once you get the first heal spell. There is no motivation for anyone to spec in magic.
