Thanks! Yeah, my biggest regret with the game as it is now is that it doesn't push the explanations of the mechanics enough. Fortunately most people seem to be figuring them out fine (and the jam build is easy enough that you don't need to to progress), but I would like to have been able to give them more focus.
I did actually have a mechanic for a kind of health recovery/armour item that used the equipment grid, but in the end for a jam game it made more sense to me to push people to use the new Guardians they were getting, as their old ones got too damaged.
Thanks again for playing!
