Took a second to get used to the control scheme but once I stopped shooting I think that freed up some brain power and I got into a rhythm of diving in between areas, using the aoe and picking up the regen. After a few attempts I finally completed the map. It made for a satisfying progression experience as I went from being barley able to move, to developing little strategies, culminating in that last perfect run.
My first instinct was to give up after the first few deaths, but I stuck through it like a Dark Souls boss and it payed off. Great game, lots of fun!
