Thank you for the feedback! You do need to be careful to choose abilities that work together. However, when you are stuck on a battle, you are given the option to swap out your artifacts for others, which I believe addresses your problem.
I didnt see that option tho. No button or anything after losing 2 or so times on the final boss. Unless I was looking in the wrong place.
Unless that was an option that wasn't in the version i was currently playing?
Also want to make sure. Does playing on the site not save your progress? Since in my case, it didn't.
