I crowd funded the game on Kickstarter and it was very much worth it. Without getting all of the golden totems, but still getting 39 of them, and getting all of the gear my playthrough on the Legendary difficulty in boost mode (instead of survival) lasted around 10 hours 30 minutes.

The boss fights are amazing, great aesthetic to the fights as well with nice designs in terms of the tactics and the appearance. There are also mini-bosses called Champions that drop equipment that you can only acquire from defeating them which is nice but it isn't required. Very much enjoyed the game and would recommend it to others.
