it's a roguelite in that you get to keep credits after you die. then the game has this blueprints system which I'm assuming you buy with the credits and perhaps also can unlock with secrets on your runs maybe. these blueprints then offer you upgrades which you can use to make the ship you take into successive runs stronger than the one you did previously. so it's the darksouls method.

then there is also crafting and upgrades you do inside a run because things like the guns you have and maybe extra bonuses to shields and hull strength and so on can be had during a run depending on what you find and craft or buy from merchants but those don't carry over.
