An interesting structure to gameplay I think mainly let down by not understanding why I should be fighting. It wasn't like we were collecting resources to buy upgrades - all it was is trying to avoid losing health. Once I had a strategy worked out there was pretty much no challenge to it and the allure of different items was diminished by the challenge purely being in acquiring them. I think there is something to mine here on the presentation and core loop - keeping in mind that the pivot axis of the circle needs to be fixed.
