Great Game!
For those who wonder, it's not (Entirely) your score that determines whether you get 100% game completion. To achieve that, you must have your armor AND weapon maxed out, while collecting the achievements in game. The achievements are:
- Slay a Dragon (Use the Divine Edge, it's much easier)
- Stashed 3000 Gold (Having 3000 in your pocket)
- Reach day #10
- Get all collection (Getting all the upgrades)
- Perform 70 000+ Damage (Mostly, stay alive long enough and you'll get this)
I'm not quite sure if there's an ending to the game (Like a cinematic or something) or if you just keep running until you die.
And a little tip: Only buy an Elixir if you don't have the money or the occasion to buy an Armor Upgrades, because those replenish your life bar as well.
