“Similarly a Metroidvania-Roguelike-Souls sort of thing, but with a different approach. It's much more Metroidvania, where you don't lose your upgrades when you die and the entire map doesn't randomize on each run. But the neat thing is that while the major points of interest like bosses and upgrades stay in the same place, the paths connecting them are randomized every time you die. So you still have to do a bit of exploring to get around even when you've already explored the whole map.”
