spent the last few days redoing the final boss. originally he was quite the let down once you've unlocked all the hidden hearts, magic upgrades, found the spirit sword and golden apple which grants double defense. with a few tweaks and a change to his final part he now poses a serious threat even at your strongest this guy hits like a truck and tests you on all the abilities you collect over the span of the game.
may need to tweak his difficulty before launch a bit but as of right now I'm happy with him. my main tester is going to trying it tomorrow. I'll go from there on any changes the final challenge may need.
looking forward to hear what everyone thinks of the ending.
