First off, I just want to say that this mod is great. I've always loved risk of rain 2, And of course the remake of RoR1, "Risk of rain returns", And so I loved the idea of RoR2 in Terraria, (Which is basically what this mod is), But this mod failed to capture a feature that RoR2 did perfectly: Replayability. In case you don't know, replayability just means that you can do more things in the game AFTER you beat the final boss. In this mod, there is a higher difficulty than normal, and that is basically it for replayabillity. But RoR2 fixed that problem by making modifiers to your run, named "Artifacts". These could make the game easier, harder, or just different than normal. So, If the creator of this mod added artifacts, that would make the replayability issue solved instantly! And you could also mix and match artifacts together in RoR2, Which adds near unlimited possibility! And that is my answer to: "the replayability issue".
